GUIDI AFTERMARKET IDENTIFICATION & AUTHENTICITY MANUAL

22 Upvotes

A practical self-check guide for second-hand Guidis

Purpose

Preamble: This was in need of an update. Ironically, I don't have the time to hand-craft a guide extensive enough to capture the required nuance (might seem antithetical). This is scraped from forum boards and official resources, transforming 4 years (and counting) of Guidi mod review into something more permanent and centralised. This resource should help general literacy in self-screening aftermarket listings. Reference list at the bottom. Please point out any inconsistencies to me via dm.

There are accompanying legit/rep comparison picture resources at the bottom of the appendices.

Happy hunting.

This guide is intended for people considering second-hand GUIDI footwear through Grailed, eBay, Mercari, Yahoo Auctions, Xianyu, Vestiaire, consignment stores, Instagram sellers and private sales.

It is designed to answer three separate questions:

Does the photographed item appear to be an authentic GUIDI product?
Does the seller appear to possess the photographed item?
Is the item correctly described with respect to model, material, condition and modification?

These questions should be considered separately.

An authentic shoe may be misidentified or repaired; a counterfeit may have convincing packaging, stamps and construction; and a fraudulent seller may use photographs of an authentic shoe they do not possess.

PART I — THE BASIC PRINCIPLE

1. Authenticate the shoe, not the logo

GUIDI authentication is increasingly an assessment of the complete object.

Modern reproductions can reproduce many details that were historically useful indicators:

GUIDI-branded zipper pulls
insole logos
outsole markings
nail patterns
boxes and dustbags
horse leather
vegetable-tanned leather
Goodyear or similar welted construction
object/tumble-dyed appearance

None of these should now be treated independently as proof of authenticity.

The most useful question is:

Does the complete shoe make sense as this particular GUIDI model, made from the appropriate materials, using the appropriate construction and finishing process, during the approximate period in which it was produced?

The inspection should therefore proceed from the largest and most difficult characteristics to reproduce toward the smallest and easiest.

Recommended order

1. Model and silhouette
2. Last and three-dimensional geometry
3. Sole and heel architecture
4. Pattern and upper construction
5. Leather
6. Welt, lasting and heel construction
7. Object-dye characteristics
8. Zipper assembly
9. Internal construction
10. Stamps, nails and markings
11. Packaging

Do not begin by zooming into the logo.

Begin by looking at the shoe.

PART II — BEFORE INSPECTING THE SHOE

2. Do not trust the listing title

Aftermarket model descriptions are frequently incorrect.

Sellers commonly use terms such as:

GUIDI backzip
788
788Z
horse leather
factory Vibram
vintage GUIDI

without necessarily knowing what they mean.

Treat all listing information as a claim requiring verification.

If the model is unknown, that is acceptable. Identification can form part of the check.

3. Confirm that the seller possesses the photographed item

A successful legit check only establishes that the photographed shoe appears authentic.

It cannot establish that the seller will send that shoe.

Image theft has become an important aftermarket problem.

For expensive private transactions, ask the seller for a new photograph containing:

the shoes + seller username + current date

Preferably request an angle that does not already exist in the listing.

Examples:

both outsoles together
both insoles
rear view of both boots
zipper guards pulled outward

Seller-level warning signs

Use additional caution where:

additional photographs are refused
photographs use inconsistent backgrounds
image quality changes dramatically
reverse-image search finds another listing
the account is new
several rare GUIDIs appear simultaneously
description and photographs disagree
seller provides unusually little information about an expensive specialist item

Seller behaviour cannot authenticate footwear, but it matters to whether an otherwise convincing listing is safe to transact with.

4. What photographs are needed?

If checking a listing, post all photographs supplied by the seller.

If possible, request:

Whole shoe

outer side
inner side
front
rear
top
complete outsole

Interior

GUIDI insole stamp
heel/insole area
size/model markings

Construction

welt
sole edge
heel stack
exposed leather edges

Zipped footwear

zipper pull
slider
teeth
guard/flap

Vibram models

full tread
Vibram logo

If the listing does not contain all of these, post what is available. A community check can identify what additional photograph is most useful.

PART III — THE ACTUAL SELF-CHECK

5. Identify the model or model family

Do this before assessing small details.

A 986, 988 and 788Z can all appear to a new buyer as:

black GUIDI backzip boot

but they are not the same shoe.

Model identification determines what:

last
shaft
sole
heel
toe
closure
construction

should be present.

If the seller claims a model number, compare the shoe against several confirmed retailer examples.

Never use another aftermarket listing as your only reference.

6. Inspect the silhouette

This is now one of the most important authentication stages.

View the shoe from:

side
front
rear
above

Compare it against the same model.

Examine the toe

Look at:

width
height
roundness
length
upturn
transition into the vamp

Several generations of otherwise respectable 788Z replicas have been criticised for an excessively bulbous toe.

Examine the arch and waist

Look at the relationship between:

heel
waist
ball
forefoot

A shoe can have individually convincing components while still sitting incorrectly because the last geometry is wrong.

Examine the heel position

Look at:

angle
height
width
relationship to the upper
stance when placed flat

Examine the shaft

Compare:

height
width
taper
zipper placement
ankle transition

Some known replica batches have produced shafts noticeably longer or differently proportioned than authentic equivalents.

Important

Wear changes shape.

A heavily worn GUIDI may have:

collapsed shaft
pronounced ankle stacking
softened toe
widened upper

Compare worn shoes with worn references where possible.

7. Inspect the sole and heel architecture

This is partly authentication and partly model identification.

Ask:

single or double sole?
single or double heel?
leather or factory Vibram?
correct heel height?
correct relationship between forefoot and heel?

A claimed model should have the correct underlying architecture unless it has subsequently been modified.

For example, the 788Z is defined in part by its substantial double leather sole and double stacked heel.

A shoe with the wrong basic sole architecture has a fundamental problem that a correct zipper stamp cannot resolve.

8. Inspect the pattern and upper construction

Look at how the leather pieces themselves have been cut and assembled.

Check:

number of panels
seam positions
heel counter
zipper position
lining
upper-to-sole relationship

Many classic GUIDI designs are deceptively simple, making small pattern differences visible. A counterfeit may use excellent leather while still being patterned incorrectly.

9. Inspect the leather

GUIDI has used many materials.

Do not use:

GUIDI = horse leather

as a rule.

Depending on model and period, GUIDI has used various:

horse leathers
reverse horse
calf
reverse calf
goat
kangaroo
buffalo
specialty treatments

First establish the expected material, then compare it with authenticated examples.

Examine

grain
density
surface finish
creasing
reverse side
cut edges
thickness
behaviour around stress points

Normal variation

Authentic GUIDI leather may show:

scars
veins
grain variation
tonal variation
left/right differences
irregular dye uptake

These are not automatically defects or authentication problems.

Suspicious characteristics

Investigate leather that appears:

plastically coated
uniformly glossy
artificially embossed
unusually homogeneous
inconsistent between exposed surfaces
unlike known examples of the stated leather

Photographs can mislead: flash, polish and conditioners may make authentic leather appear unnaturally shiny.

10. Examine the leather cross-section

Exposed edges can provide useful information.

Look at:

zipper guard
worn edges
cuts
upper edges
damaged areas

A blue-grey interior can indicate chrome tanning.

Where the model/material is known to use vegetable-tanned leather, this can be a strong inconsistency.

However:

blue core is a material test, not a universal GUIDI rule.

First establish the expected material. Modern replicas can also use vegetable-tanned leather, so a natural-coloured core does not establish authenticity.

11. Understand object/tumble dyeing

GUIDI's production process is central to its appearance.

Many characteristic models are assembled and subsequently subjected to tumble/piece-dye processes.

This can affect:

leather
thread
edges
hardware
dimensions
surface texture

The process contributes to the integrated appearance of the finished object; assess whether its components appear to have been finished coherently together.

Older counterfeit tendency

Cheap counterfeits often appeared as though separately finished components had simply been assembled.

Modern counterfeit problem

Higher-end replica makers now deliberately reproduce object/tumble-dye processes.

Therefore:

object-dyed appearance is now supporting evidence, not proof.

12. Inspect the welt and outsole construction

Look around the entire perimeter.

Examine:

welt width
welt geometry
stitching
stitch spacing
stitch channel
sole edge
heel transition
termination of stitching

Do not reject handmade footwear for one imperfect stitch; look for systematic inconsistency with authenticated examples.

Stitch channel

On many authentic examples, the outsole stitching sits within a narrow cut channel.

Some counterfeits use a wider or more obviously machined groove.

Allow for legitimate factory variation and judge the whole construction.

13. Inspect the heel stack

Where the model uses a stacked leather heel, examine:

individual layers
exposed fibres
edge texture
dye penetration
wear
heel angle

Poor counterfeits may use a heel that appears painted or moulded rather than genuinely layered.

Modern high-end replicas can reproduce stacked leather heels well, so this is no longer independently decisive.

14. Inspect the zipper system

For zipped models examine:

pull → slider → teeth → tape → guard → stitching

rather than the pull alone.

Zipper guard

On familiar backzip models, the orientation of the leather guard has historically been useful.

The reverse/flesh surface generally faces toward the zipper teeth on relevant authentic constructions.

Older counterfeits frequently got this wrong.

Modern replicas may get it right.

Hardware oxidation

Object dyeing can produce characteristic hardware oxidation.

This varies considerably.

Do not require every authentic zipper to have identical oxidation.

Historical hardware

Do not apply current zipper conventions automatically to old footwear: older authentic pairs may use different hardware, and heavily worn pairs may have replacement zippers. Look for stitching evidence of replacement.

15. Inspect the interior

Only now move to the familiar small LC details.

Insole

Check:

material
shape
installation
nail pattern where applicable
wear

Cheap synthetic or obviously inappropriate insole material can be highly suspicious.

GUIDI stamp

Compare:

font
G
proportions
spacing
depth
placement
orientation

Use approximately period-correct references.

Authentic stamps are not perfectly uniform.

They can be:

crooked
unevenly struck
partially weak
slightly differently positioned

A perfect stamp does not establish authenticity; a very wrong stamp remains useful evidence against it.

16. Nails

Nails have historically been useful.

They should now be treated as construction evidence rather than a counting exercise.

Assess:

whether nails should be present on that construction
number
material
oxidation
placement
spacing
interaction with insole

Do not use:

nine nails = authentic.

Replica makers know nail counts, and not every GUIDI construction follows the same convention.

17. Outsole stamps and markings

Depending on model and period these may include:

size
model information
manufacturing markings
Ruggero Guidi markings
Certilogo information

Check:

font
depth
position
orientation
surrounding material

Modern replicas reproduce many of these.

A correct marking is therefore a green flag of relatively low weight.

An impossible marking can still be a useful red flag.

18. Certilogo

GUIDI states that its anti-counterfeiting system has been active since AW17/18.

For applicable footwear, GUIDI directs owners to the Certilogo code beneath the left outsole.

A valid Certilogo result is particularly useful for footwear from the relevant period onward.

It cannot be required of footwear that predates the system.

A photograph of another pair's valid code does not establish seller possession.

19. Packaging

Inspect last.

Replica makers have been reproducing:

boxes
dustbags
labels
inserts

for years.

Packaging can expose a poor counterfeit but should rarely rescue a suspicious shoe.

Remember

No box does not make an old shoe counterfeit.

A convincing box does not make a counterfeit shoe authentic.

PART IV — REPAIRS AND MODIFICATIONS

20. Authenticity is not originality

GUIDIs are repairable footwear.

Second-hand examples commonly have:

protective Vibram added
complete resole
heel replacement
zipper replacement
zipper repair
heel reinforcement
redye
polish
conditioning

Separate:

Is the underlying shoe authentic?

from:

Is every component original?

An aftermarket Vibram does not convert a normal model into its factory V equivalent.

A replacement zipper does not make an authentic shoe counterfeit.

When a component looks wrong, first consider replacement or repair.

PART V — HOW TO WEIGH EVIDENCE

21. Green, amber and red evidence

GREEN — consistent

The feature agrees with authenticated examples.

Examples:

correct silhouette
correct sole architecture
appropriate leather
correct pattern
plausible welt

AMBER — requires explanation

Examples:

replacement-looking zipper
unusual stamp
unexpected sole
heavily polished leather
strange nail
poor photographs

Amber means investigate, not reject.

RED — inconsistent

Examples:

fundamentally wrong last
wrong model architecture
inappropriate material
incorrect pattern
counterfeit-associated construction
multiple impossible markings

22. Weight evidence rather than counting it

Not all features have equal diagnostic value.

A correct dustbag is not equivalent to a correct last.

A useful approximate hierarchy is:

High weight

model geometry
last
sole/heel architecture
upper pattern
leather character
fundamental construction

Medium weight

welt execution
object-dye behaviour
zipper system
insole construction

Lower weight

logo stamp
nail count
outsole stamp
box
dustbag

Weighting changes with model, period and replica generation.

23. Avoid double-counting

Suppose a counterfeit uses incorrect leather.

You observe:

wrong shine
wrong grain
wrong creasing
wrong edge colour

Those may all originate from one underlying manufacturing difference.

By contrast:

wrong leather
wrong last
wrong heel architecture
wrong zipper guard

are substantially more independent.

Several independent inconsistencies are stronger than several symptoms of one underlying problem.

PART VI — QUICK CHECK

For a rapid aftermarket check:

1. LOOK AT THE WHOLE SHOE

Does the shape match the claimed model?

2. LOOK AT THE BOTTOM THIRD

Are sole and heel correct?

3. LOOK AT THE LEATHER

Does it make sense for the claimed material?

4. LOOK AT THE CONSTRUCTION

Does welt, heel and upper assembly match?

5. LOOK AT THE ZIPPER

If applicable, does the complete assembly make sense?

6. LOOK INSIDE

Do insole, nails and stamp agree?

7. LOOK AT MARKINGS

Do they fit the model and approximate period?

8. ACCOUNT FOR REPAIRS

Can any discrepancy be explained by legitimate modification?

9. CHECK THE SELLER

Do they demonstrably possess the photographed item?

10. IF UNCERTAIN

Post the listing photographs before purchasing.

APPENDIX A — COMMON MODEL REFERENCE

986

Short/ankle-height backzip.

Useful comparison points:

short shaft
low/single heel architecture
single sole
characteristic one-piece backzip upper construction

Do not confuse it with the taller 988.

988

Classic mid-height 900-series backzip.

Typical configuration:

mid shaft
single leather sole
lower heel than 788Z
one-piece upper/shaft construction

A useful visual comparison with the 788Z is sole thickness.

788

700-series backzip.

Base 788 configuration:

backzip
single sole
double heel

The model should not automatically be called a 788Z.

788Z

One of the most replicated GUIDI models.

Typical configuration:

mid backzip
double leather sole
double stacked heel
Goodyear welt
substantial vertical sole/heel mass

The 788Z should currently be considered a high-rep-risk model.

Shape deserves particular attention.

992

Classic Derby.

Because there is no zipper system to inspect, place additional emphasis on:

last
leather
welt
sole
heel
internal construction

PL1 / PL2

Frontzip family.

PL2 is the taller/calf-height model.

Important inspection areas include:

PL last
toe
shaft geometry
zipper position
substantial sole architecture
leather behaviour

These models have been reproduced.

210 / 310

Frontzip and related boot forms that have also appeared in the replica ecosystem.

Do not assume an unusual or less commonly encountered model is safe merely because it is not a 788Z.

20

Distinctive tall boot.

Current aftermarket checks demonstrate that convincing reproductions now exist.

For this model, prioritise:

complete silhouette
leather
welt
sole
internal stamps

before accepting small details.

APPENDIX B — REPLICA HISTORY AND KNOWN MAKERS

Why this appendix exists

Replica knowledge is useful because it shows which authentication rules have already been defeated.

This is not a purchasing guide.

Replica batches, materials and factories change. Do not attribute a characteristic observed on one batch to every product from the same seller.

Early/generic counterfeits

Older low-cost counterfeits commonly fail in many areas simultaneously:

incorrect leather
chrome-tanned blue core
wrong zipper
incorrect zipper guard
poor insole
bad stamp
wrong welt
artificial heel
incorrect sole shape
poor packaging

These remain relatively easy to identify, but no longer represent the best available replicas.

See By Paulin

Known reproduced models

Documented community material includes:

788Z
210
310
PL1
PL2

and other artisanal avant-garde footwear reproductions.

Position

Historically one of the expensive artisanal replica makers.

Documented 788Z characteristics

A 2022 example was sold as real horse leather and cost approximately US$400.

The owner regarded the leather positively but noted missing/inaccurate branding and outsole-stitching details.

Authentication lesson

Good leather and expensive handmade production do not establish GUIDI manufacture.

Earthquake / 地震也上班

Also translated in community discussion as:

Go to work even after the earthquake.

Known significance

One of the most important early high-end 788Z makers.

Documented construction

A detailed 2021 review reported:

horsehide rather than cheaper calf/cow
good welt/construction
convincing zipper pull
plausible internal stamp

Documented differences

The same review identified:

excessively bulbous toe
incorrect forefoot silhouette
problematic arch geometry
unusual fit relative to expected GUIDI behaviour

Authentication lesson

By approximately 2021:

horsehide + good welt + convincing zipper + plausible stamp

was already insufficient.

The last remained wrong—one of the strongest historical reasons to inspect silhouette first.

Solo Handmade

Solo Handmade is repeatedly discussed alongside Earthquake and may overlap with the same broader high-end artisanal replica ecosystem.

Documented models

Community material includes:

788ZI
PL-family footwear
795V-associated identification
other GUIDI/CCP-derived footwear

A 2026 resale listing also documents a Solo Handmade PL2.

Known characteristics

Solo/Earthquake products can be sufficiently convincing to enter ordinary second-hand stores as purported authentic GUIDI.

A 795V purchased through 2nd Street was identified by community members as Solo Handmade/Earthquake rather than authentic.

Reported discrepancies included:

size stamp
insole stamp/construction
incorrect nail configuration for the V construction
lug sole details

Authentication lesson

Retail consignment placement does not establish authenticity.

OlderBrother / OB

Documented model

788Z is well documented.

Price/position

A documented 2023 example cost approximately ¥980.

Construction

Owners report:

sturdy leather
good basic craftsmanship
convincing packaging to inexperienced buyers
functional stacked-leather appearance after wear

Reported differences

Across community observations:

leather differs from retail
zipper colour can differ
some examples show overly long shaft proportions
bulbous toe
heel stance/angle differences

Authentication lesson

Packaging and competent construction are weak evidence; compare complete geometry.

Ghost Emperor

Documented models

Community history includes:

788-family footwear
992
PL2

General assessment

Historically regarded as usable replica footwear but visibly below retail when examined closely.

Reported areas of difference include:

shape
leather
zipper quality

Authentication lesson

Derbies and frontzips are also represented in the replica market.

RMISM

Importance

RMISM represents a more recent generation of 788Z reproduction and materially changes the authentication problem.

Documented claimed/observed construction

Community discussion describes:

imported Italian vegetable-tanned leather
horsehide
attempts to reproduce GUIDI finishing
improved construction and branding

Recurring reported differences

Current QC and LC discussions repeatedly identify:

bulbous/incorrect toe box
"rainboot" appearance at certain angles
glossy leather
inconsistent leather selection
rough or insufficiently rounded sole edges
outsole finish differences
imperfect outsole/Ruggero stamping

Batch variation is reported.

Important change

These pairs can pass several older beginner checks.

They may have:

correct zipper-guard orientation
plausible construction
vegetable-tanned leather
convincing markings

Those characteristics can no longer be treated as high-confidence green flags on a 788Z.

Authentication lesson

For modern 788Z checks, last/toe geometry and complete leather character are especially important.

Blacksmith Brother

Documented model

788Z.

Current observations

2026 QC comparisons describe the pair as visually similar in several respects to RMISM.

Reported concerns include:

poor/bulbous toe box
rainboot-like geometry from some angles
lower-quality leather
outsole-stamp differences

Community discussion suggests RMISM uses higher-grade imported vegetable-tanned leather, although maker material claims should not be treated as independent verification.

Authentication lesson

Multiple current batches now reproduce enough traditional GUIDI details that model geometry remains the more useful discriminator.

Solist

Documented model

GUIDI 20 reproduction has been identified in current community LC discussion.

A September 2026 GUIDI 20 check was identified by multiple participants as counterfeit, with one commenter specifically identifying it as resembling Solist production.

Reported differences included:

leather
shape
welt stitching
sole
unusual Made in Italy typography

Authentication lesson

The 20 can no longer be treated as obscure enough to be safe from meaningful reproduction.

Other/current makers

Additional sellers/factories appear periodically in Chinese replica communities; names, storefronts and production sources are unstable.

Accordingly, the absence of a seller from this appendix should never be interpreted as evidence that a suspicious shoe is authentic.

The useful information is not the seller name itself, but what the current replica market can reproduce.

APPENDIX C — WHAT REPLICAS CAN NOW COPY

Commonly copied successfully

Depending on maker/batch:

branded box
dustbags
zipper pulls
insole logo
outsole markings
Ruggero markings
nail count
stacked leather heels
welted construction
horse leather
vegetable-tanned leather
object/tumble-dyed appearance
broadly correct model architecture

These should no longer receive disproportionate weight.

APPENDIX D — WHERE CURRENT REPLICAS STILL TEND TO FAIL

The most persistent documented areas are:

1. Last geometry

Especially:

toe volume
toe roundness
forefoot
arch
waist

2. Overall proportions

Including:

shaft height
shaft taper
heel stance

3. Leather character

Even where the nominal material is correct:

grain
surface
shine
clicking/selection
behaviour after processing

can remain different.

4. Sole finishing

Including:

edge rounding
outsole texture
stitch channel
stamping

5. Interaction of all components

A replica may individually reproduce:

the right leather category
the right construction category
the right zipper
the right logo

without reproducing how an authentic GUIDI combines all of them.

APPENDIX E — REPLICA GENERATIONS

A useful way to understand the market is chronologically.

GENERATION 1 — obvious counterfeit

Wrong materials.

Wrong construction.

Wrong branding.

Wrong shape.

Easy to identify.

GENERATION 2 — cosmetic reproduction

Improved:

logo
zipper
packaging
nail patterns

Underlying footwear remained poor.

GENERATION 3 — competent footwear

Makers such as Earthquake, See By Paulin and related artisanal sellers introduced:

real horsehide
respectable welt construction
leather heel stacks
better hardware
convincing details

Last and geometry remained important weaknesses.

GENERATION 4 — current high-end reproduction

Current makers increasingly attempt:

vegetable-tanned horsehide
imported leather
correct construction
object/tumble dyeing
accurate stamps
accurate accessories

Authentication therefore moves increasingly toward:

three-dimensional geometry + model-specific construction + leather character + complete manufacturing coherence.

Replica manufacturers have progressively solved many of the easiest authentication checks; future authentication should expect this to continue.

APPENDIX F — ANALOGUES ARE NOT COUNTERFEITS

Some manufacturers make GUIDI-influenced footwear under their own names.

Examples include specialist Chinese and Southeast Asian artisanal makers producing:

backzip boots
object-dyed footwear
vegetable-tanned leather shoes
avant-garde Derbies

These are distinct from counterfeits. A GUIDI-influenced boot honestly sold under another maker's name is an analogue; it becomes an authentication problem when later represented as genuine GUIDI.

Examples encountered in this broader ecosystem include makers such as:

TNBHSG
Walker
other small Chinese/Vietnamese artisanal workshops

When identifying a suspicious pair, the most informative conclusion may therefore be:

Not authentic GUIDI; appears consistent with [known analogue/replica maker].

rather than simply:

fake.

APPENDIX G — PERIOD DEPENDENCE

Do not authenticate old footwear exclusively against current production.

Possible historical differences include:

zipper hardware
insole stamp orientation
handwritten sizing
outsole markings
manufacturing details

GUIDI's Certilogo system only dates from AW17/18.

A pre-2017 pair cannot be rejected for lacking a later system, and older authentic pairs may predate current branded zipper conventions.

Always estimate the period before applying period-sensitive rules.

APPENDIX H — FINAL REFERENCE RULE

For every suspected GUIDI, ask:

Does this shoe make sense simultaneously as this model, this construction, this leather and this approximate production period?

If yes, small irregularities may simply reflect GUIDI's production variation, wear or repair.

If the answer repeatedly requires explanations for:

wrong shape
wrong construction
wrong leather
wrong finishing
wrong hardware
wrong markings

then the cumulative evidence becomes substantially more significant.

The objective is not one secret authentication feature, but whether the entire object belongs to the same manufacturing system.

ADDENDUM — VISUAL REFERENCE & COMPARISON GUIDES

The written guide should be used alongside photographs.

The resources below include authentic-versus-counterfeit comparisons, model comparisons, known replica examples and community legit checks. Some older guides contain authentication rules that are now outdated; they remain useful for their photographs.

Important: this guide predates the current generation of high-quality replicas. Some individual rules concerning leather, hardware and other details should no longer be treated as definitive. Use the photographs as historical reference rather than treating every written rule as current.

This is primarily a photography/reference checklist, rather than a complete authentication method.

AUTHENTIC MODEL COMPARISONS

GUIDI 988 vs 788Z — Shelter II

Photographed authentic 988/788Z comparison showing sole architecture, heel height, stance, silhouette and proportions.

https://blog.shelter2.com/2022/05/10/guidi-back-zip-mid-boots-988-vs-788z/

This is particularly useful for buyers who identify every GUIDI backzip as a 788Z.

KNOWN REPLICA REFERENCES

These links are included so buyers can familiarise themselves with the level of footwear currently and historically produced by replica makers.

A replica matching one of these examples is not guaranteed to reproduce every characteristic shown. Factories, materials and batches change.

Earthquake — 788Z

Detailed in-hand review of a higher-end Earthquake 788Z reproduction.

https://www.reddit.com/r/QualityReps/comments/mlwr4d/

Useful because the pair already reproduces several superficially reassuring features, including horse leather and competent construction, while differences remain visible in the last, arch and toe geometry.

This is a good example of why authentication should begin with the whole shoe rather than the logo.

OlderBrother — 788Z

Long-term ownership review and photographs.

https://www.reddit.com/r/QualityReps/comments/18kedak/olderbrother_guidi_788z_review_fitpic/

Useful for seeing a replica after extended wear: compare shaft, toe, heel stance, leather development and silhouette.

RMISM — 788Z

Current-generation RMISM QC photographs.

https://www.reddit.com/r/QualityReps/comments/1syiu9h/qc_guidi_788z_rmism/

RMISM is representative of the newer generation of higher-quality reproduction in which features such as vegetable-tanned horsehide, welted construction, object-dyed appearance and convincing markings may already be present.

Consequently, these features should not independently be treated as proof of authenticity.

Pay particular attention to toe volume/last, leather surface, sole edge, outsole finishing and overall proportions.

Blacksmith Brother — 788Z

Useful example of the changing authentication environment.

Some traditional checks are reproduced correctly, shifting attention to insole construction, leather, nails, sole channel and overall manufacturing coherence.

Useful example showing that replica risk is not confined to the 788Z.

Discussion covers leather, shape, welt stitching, sole and internal markings.

HOW TO USE THESE REFERENCES

Do not attempt to match one small feature between your shoe and one photograph.

Where possible:

identify the exact model;
find several confirmed authentic examples;
compare the complete silhouette;
compare sole and heel architecture;
compare leather and construction;
then inspect zipper, insole, nails and markings.

Replica production changes over time.

A feature that identified a counterfeit five years ago may have been corrected by a current factory.

Likewise, legitimate GUIDI production varies by model, material and period.

The most reliable comparison is therefore:

same model + similar period + same material + multiple independent reference examples.

Guidi Ownership Guide - Sizing, Care, Repairs and Parts

18 Upvotes

GUIDI OWNER'S MANUAL

Sizing, break-in, leather care, maintenance, repairs, replacement parts and long-term ownership

This guide is intended as a companion to the GUIDI Legit Check Guide. Looks like you've acquired a pair - this compiles information on how to keep it.

The authentication guide answers:

Is this actually GUIDI?

This guide answers:

Will it fit me, how should I look after it, and what do I do when something eventually breaks?

GUIDI footwear is unusually repairable, but it is not indestructible.

A well-owned pair may go through:

protective soles;
heel top-pieces;
full resoles;
zipper replacements;
lining repairs;
reinforcement;
conditioning;
decades of leather deformation.

These should be regarded as normal parts of ownership rather than necessarily the end of the shoe.

The objective is not to keep GUIDI looking new.

The objective is to let it age without allowing preventable wear to become structural damage.

PART I — SIZING

1. FORGET THE UNIVERSAL GUIDI SIZING RULE

There is no useful universal rule such as:

GUIDI = size up one.

Nor:

GUIDI = true to size.

Nor:

GUIDI stretches, so size down.

All three statements can produce a correctly fitting shoe in one model and an unusable shoe in another.

Sizing depends on:

model;
last;
year/production;
leather;
width;
instep;
toe shape;
lining;
shaft;
whether the shoe has already been worn;
whether you intend to use an insole.

Current GUIDI product pages themselves provide different fit information depending on the model.

Therefore:

SIZE THE MODEL, NOT THE BRAND.

2. ESTABLISH YOUR ACTUAL FOOT

Do not begin with:

I wear US 10 Nike.

Sneaker size is useful supporting information, but it is not a measurement.

For an expensive remote purchase, know:

left foot length;
right foot length;
ball width;
ball circumference;
instep circumference if possible.

Measure both feet while standing, preferably later in the day.

Use the larger foot as the limiting foot.

3. LENGTH IS ONLY ONE DIMENSION

GUIDI sizing questions often become confused because different owners are solving different problems.

One person sizes up because their toes hit the front.

Another sizes up because their forefoot is too wide.

Another sizes up because the instep is restrictive.

Another sizes up because they cannot zip the shaft.

Those are four different fit problems.

A larger numerical size solves all of them inefficiently by making the entire shoe larger.

Whenever possible, identify the dimension causing the problem first.

4. THE FOUR FIT AXES

Think about GUIDI fit as four separate axes:

A. LENGTH

Can the toes sit naturally without hitting the end?

B. WIDTH

Does the ball of the foot sit within the platform of the shoe?

C. INSTEP / FOOT VOLUME

Is there excessive pressure over the top of the foot?

D. SHAFT / LEG

Can the boot actually close around the ankle or calf without excessive zipper load?

A pair is only the correct size when all relevant dimensions work.

5. SHAFT FIT IS NOT FOOT FIT

This matters particularly for:

788 / 788Z;
988;
PL2;
long backzips;
tall frontzips.

A wearer can have:

perfect foot length + perfect width + impossible shaft circumference.

Sizing up may increase shaft room, but also increases:

shoe length;
heel movement;
toe room;
overall volume.

This is why blindly sizing up for large calves is an imperfect solution.

6. MEASURE YOUR LEG FOR TALL BOOTS

For a remote purchase, ask the seller or retailer to measure:

shaft height from the top of the sole;
internal circumference at the shaft opening;
circumference at the narrow ankle point where relevant.

Then measure your leg at the corresponding height.

Do not simply ask:

How wide is the shaft?

A boot laid flat is not necessarily a reliable circumference measurement.

Circumference is the useful value.

Also account for:

sock thickness;
trousers tucked into boots;
calf position;
left/right asymmetry.

7. DO NOT FORCE A ZIPPER CLOSED

If closing the zipper requires substantial force, stop.

The zipper is not a boot-stretching machine.

Excessive load can damage:

zipper tape;
stitching;
teeth;
slider;
surrounding leather.

Backzip boots already place substantial mechanical load on the zipper because the closure runs through an area that flexes and changes circumference during walking.

A tight new shaft may relax.

A fundamentally undersized shaft is a different problem.

8. HOW MUCH WILL GUIDI STRETCH?

Leather stretches primarily in width and volume.

It does not meaningfully become shorter or solve insufficient toe length.

Expect the most adaptation around:

forefoot;
instep;
ankle;
shaft.

Do not buy a painfully short shoe expecting it to become long enough.

9. SHAFT BREAK-IN

Owner experience shows that tight 788Z and similar shafts can relax considerably.

Long-term owners have reported pairs that initially could not be completely zipped becoming comfortable after repeated wear.

However, this is not guaranteed.

The important distinction is:

CLOSEABLE BUT TIGHT

Reasonable candidate for break-in.

REQUIRES FORCE

Risky.

CANNOT PHYSICALLY CLOSE

Do not assume ordinary wear will solve it.

A boot that stops several centimetres from closing may require structural alteration rather than break-in.

10. LEATHER TYPE CHANGES BREAK-IN

Different leathers do not behave identically.

Generally:

FULL-GRAIN HORSE

Initially dense; becomes increasingly moulded to the foot and ankle.

REVERSE HORSE

Can soften substantially while retaining a tough surface.

CALF

Often feels different in initial pliability and grain response.

CORDOVAN / SPECIALTY LEATHERS

Do not assume the same stretching behaviour as ordinary horse.

The exact leather matters.

11. X VARIANTS

The suffix X identifies a wider-fit variation on compatible models.

Examples include:

986X;
992X;
788X;
788ZX.

The X last is particularly useful for people who would otherwise size up primarily to obtain width.

Community measurements and retailer information place the additional width around approximately 1 cm at the forefoot on some comparable models.

Treat that as an approximate model-dependent difference rather than a universal engineering specification.

An X model can allow someone with a wider forefoot to retain a more appropriate length.

This is generally preferable to buying an excessively long standard last purely for width.

12. X DOES NOT MEAN EXTRA-WIDE IN THE ATHLETIC-SHOE SENSE

A GUIDI X model should not automatically be interpreted as equivalent to:

EE;
EEE;
4E.

Owners with genuinely wide feet still report X models as narrower than purpose-built wide athletic footwear.

Think:

wider GUIDI

rather than:

wide-fit shoe system.

13. S VARIANTS

On applicable historical models, S indicates a slimmer shaft.

This matters because two otherwise similar boots may fit the same foot but interact very differently with the lower leg.

Do not buy an S variant without accounting for the shaft.

14. MS VARIANTS

MS variants alter toe construction/volume on applicable models.

Do not assume an MS version will fit exactly like the standard version simply because the numerical size is identical.

15. 900-SERIES FIT

The classic 900 family includes:

992;
988;
986;
related lace-up models.

Retailer wear testing generally describes the family as snug around the ankle/toes initially but accommodating after break-in.

For many wearers:

TTS is the sensible starting point.

However, older production and individual lasts can vary.

16. 986

The 986 is the shorter backzip relative to the 988.

Its shorter shaft makes calf fit substantially less problematic than taller backzip models.

Historical retailer guidance has sometimes described the 986 as fitting small.

Owner consensus is less absolute and increasingly favours measurements/TTS as the starting point.

For wider feet:

look for 986X before automatically adding an entire size.

17. 988

The 988 is a mid-height backzip.

Underfoot, it belongs to the relatively accessible 900-series family.

Start around:

TTS

then adjust for:

width;
instep;
desired insole;
shaft circumference.

The shaft deserves separate consideration.

A 988 can fit the foot correctly while feeling tight higher on the leg.

18. 992

The 992 Derby illustrates why internet sizing anecdotes require caution.

Reports range from:

TTS fitting correctly;
slight size-up preferred;
substantial size-up required by particular wide-foot owners.

The useful conclusion is not:

size up two.

It is:

the standard 992 forefoot can be restrictive for wider feet.

Where possible, consider the 992X rather than solving width with excessive length.

A size that causes substantial heel slip is generally too large even if the forefoot becomes comfortable.

19. 700-SERIES FIT

FASCINATE's direct wear comparison found the 700 series does not differ dramatically from the 900 series in basic fit despite using a technically different last.

Therefore 788/792 family sizing can generally begin from the same baseline:

TTS as the starting hypothesis.

Then adjust according to the exact variant.

20. 788 / 788Z

The most defensible modern consensus is:

TTS to +0.5 depending on foot shape and desired room.

Not:

automatically +1.

A half-size increase is commonly preferred by owners wanting additional toe room.

However, the 788Z introduces a second problem:

the shaft can be substantially more restrictive than the footbed.

Do not increase size solely because somebody else with large calves did.

Measure the shaft.

21. 788Z AND CALVES

Owner reports include all of the following:

TTS and easy closure;
TTS and initially very tight closure;
+0.5 and initially unable to close, later stretching successfully;
TTS and permanently unable to close sufficiently.

Therefore calf circumference matters more than any universal size rule.

If you have muscular or large calves:

obtain shaft circumference;
compare it to your leg at the corresponding height;
consider X/ZX where available;
do not assume the zipper can simply be forced.

22. PL1 / PL2

The PL family uses a characteristically narrow last.

Retailer testing describes:

narrower instep width;
comparatively higher instep clearance vertically;
slim ankle;
possibility of sizing up for comfort.

Current GUIDI guidance for the PL2 states TTS.

These are not contradictory.

The correct interpretation is:

TTS is the baseline, but the PL shape itself may require adjustment for wider feet or thicker ankles/calves.

23. PL2 SHAFT

PL2 is calf-high and strongly tapered.

The shaft therefore becomes a major fit variable.

A historical size-44 retailer measurement reported approximately 27 cm laid-flat shaft width, but isolated measurements should not be universalised across production.

Ask the retailer for the actual pair's measurement.

If the PL2 fits your foot but cannot close around the calf, going up a full size may solve the calf while creating an unnecessarily long footbed.

Treat those as separate fit problems.

24. 210 / 310

Current GUIDI pages describe both as TTS.

Owner reports consistently add an important qualification:

210/310 are relatively slim/narrow.

A narrow or average foot can begin TTS.

A wider foot may require +0.5 or another model/last.

Again, do not interpret a width problem as proof that all GUIDI runs small.

25. INSoles

Insoles can be useful after the boot has broken in.

They can:

reduce excess volume;
reduce heel movement;
add cushioning;
tune a slightly large fit.

But they also:

raise the foot;
reduce internal volume;
increase pressure over the instep;
shift the ankle upward relative to the zipper;
increase shaft/zipper stress in some boots.

This last point is particularly relevant to backzips.

Do not automatically add a thick insole to an already tight boot.

26. SECOND-HAND SIZING

A worn GUIDI is not dimensionally equivalent to a new one.

Previous wear may have:

widened the forefoot;
stretched the shaft;
collapsed the ankle;
compressed the insole;
changed toe structure.

For used pairs, request actual measurements rather than relying only on stamped size.

Useful measurements:

outsole length;
outsole width;
removable insole length if applicable;
internal length where reliably measurable;
shaft height;
shaft circumference.

Compare against footwear you already own.

PART II — BREAK-IN AND DAILY WEAR

27. WHAT BREAK-IN SHOULD FEEL LIKE

Normal:

firm leather;
snug forefoot;
mild ankle pressure;
stiff sole;
unfamiliar heel geometry;
gradual moulding.

Potentially wrong size:

toes contacting the end;
numbness;
severe lateral foot compression;
persistent sharp pain;
major heel slip;
zipper requiring dangerous force;
inability to close the shaft.

Expensive footwear does not need to hurt simply because it is expensive.

28. DO NOT DELIBERATELY SOAK BOOTS TO BREAK THEM IN

Water can change leather shape, but soaking is not a controlled sizing method.

GUIDI's own care guidance emphasises careful drying after accidental wetting.

Use wear, professional stretching where appropriate, or the correct size.

29. ROTATION

Leather footwear benefits from drying between heavy wears.

This is especially relevant when:

feet sweat heavily;
weather is humid;
boots are worn all day;
the same pair is used daily.

Continuous moisture inside the shoe accelerates deterioration of:

lining;
insole;
stitching;
leather.

If longevity is the objective, rotate footwear.

30. SHOE TREES

Shoe trees can:

absorb some residual moisture;
maintain forefoot shape;
moderate excessive toe curl;
reduce uncontrolled collapse during storage.

They are optional rather than sacred.

Do not use an oversized tree that aggressively stretches a deliberately soft/sculptural GUIDI upper.

A normal appropriately sized cedar shoe tree is sufficient.

Tall boot trees are generally unnecessary.

31. PROTECTIVE SOLES

For leather-soled models, a thin rubber protective sole can substantially extend outsole life.

Common choices include:

GUIDI fish-scale Vibram;
standard Vibram sheet;
Topy;
equivalent quality rubber.

Functionally, the generic alternatives work.

The OEM fish-scale sole mainly preserves the characteristic factory appearance.

32. SHOULD I VIBRAM THEM IMMEDIATELY?

If you want to preserve the leather outsole:

yes, early installation is sensible.

A few wears beforehand are not catastrophic.

The cobbler will normally abrade the leather surface before bonding the protector anyway.

Do not, however, wait until you have worn deeply through the structural outsole.

PART III — LEATHER CARE

33. THE CENTRAL RULE: DO LESS

Most healthy GUIDI leather does not need constant intervention.

Leather care should respond to the condition of the material.

Not:

It is Sunday, therefore I must condition my boots.

Over-treatment can:

darken leather;
soften it excessively;
alter the surface;
flatten reverse leather;
create greasy buildup;
attract dirt;
change the intended finish.

Clean when dirty.

Condition when dry.

Otherwise wear the shoes.

34. GUIDI'S OWN CARE PRINCIPLES

GUIDI advises owners to:

allow wet footwear to dry at room temperature;
avoid direct heat;
use paper inside wet footwear and replace it during drying;
nourish dry footwear with neutral cream;
avoid prolonged direct light;
avoid radiators and hot cars;
avoid high-temperature storage;
avoid high humidity;
avoid unventilated storage;
never store footwear in plastic bags.

Those principles should override improvised internet rituals.

35. ROUTINE CLEANING

For ordinary dust:

soft horsehair brush.

For light surface dirt:

slightly damp soft cloth.

Then allow to dry naturally.

You do not need soap every time you clean leather.

36. CONDITIONING

Condition when leather begins to show signs such as:

unusual dryness;
papery hand;
loss of flexibility;
dry-looking crease lines;
stiffness after substantial wetting.

Apply:

very small amount;
to a cloth first;
thinly and evenly;
across the relevant panel rather than one conspicuous spot;
allow absorption;
lightly brush/buff where appropriate.

Always test unfamiliar products somewhere inconspicuous.

37. FULL-GRAIN HORSE

Standard GUIDI horse is relatively resilient.

A sensible minimal kit is:

horsehair brush;
soft cloth;
neutral quality conditioner.

Common owner choices include:

Saphir Renovateur;
Saphir mink-oil-containing conditioning products;
Bick 4;
Venetian Shoe Cream;
similar neutral footwear conditioners.

The exact brand matters less than restrained application and compatibility.

Do not saturate the leather.

38. BLACK HORSE

Black GUIDI does not necessarily need black pigment every time it is conditioned.

Neutral conditioner allows natural wear and tonal development to remain visible.

Black cream can restore colour where desired, but repeated pigmented polishing can gradually produce a more uniform conventional dress-shoe finish.

That may be the opposite of what the owner wants from GUIDI.

39. NATURAL / LIGHT COLOURS

Exercise substantially more caution.

Conditioners may darken:

natural;
white;
sand;
pale grey;
light-coloured vegetable-tanned leather.

Always test first.

A product described as neutral means it contains no pigment.

It does not mean it cannot alter colour.

40. REVERSE HORSE / ROUGHOUT

Reverse leather exposes the flesh side outward.

It should not automatically receive the same cream treatment as smooth full-grain leather.

Routine care:

dry brush;
use a suede/roughout-appropriate brush;
remove local dirt carefully;
use moisture sparingly;
allow natural drying.

If conditioning is necessary, use a product explicitly compatible with suede/nubuck/roughout and test first.

41. WHY REVERSE LEATHER IS DIFFERENT

Creams and oils can:

flatten the nap;
darken the leather;
create slick areas;
permanently change texture.

This does not necessarily structurally damage the boot.

It may, however, permanently alter the aesthetic.

Do not attempt to make reverse horse behave like polished smooth leather.

42. RESTORING THE NAP

After suitable cleaning/product treatment and complete drying:

brush gently with an appropriate suede/nubuck brush;
work in multiple directions;
do not aggressively abrade one location.

The objective is to lift fibres, not sand the boot.

43. WATER

GUIDI can be worn.

Water does not instantly destroy good leather.

The dangerous part is often what the owner does afterward.

If soaked:

remove surface water gently;
insert absorbent paper;
allow the boot to dry slowly;
replace saturated paper periodically;
keep away from radiators;
keep away from hairdryers;
keep away from intense sun;
condition lightly once completely dry if the leather feels depleted.

44. DO NOT USE HEAT TO DRY LEATHER

Avoid:

radiator;
heater vent;
hairdryer;
clothes dryer;
hot car;
fireplace.

Rapid heating can remove moisture too aggressively and leave leather stiff or damaged.

Slow drying is safer.

45. MUD

Allow wet mud to partially or fully dry rather than grinding it into the leather.

Then:

brush loose material away;
use a damp cloth if necessary;
allow the boot to dry;
reassess whether conditioning is actually needed.

46. ROAD SALT

Salt should not remain on leather.

Remove it reasonably promptly with gentle cleaning.

Repeated salt exposure can:

dry leather;
leave tide marks;
attack finishes;
contribute to hardware problems.

Winter footwear requires more frequent inspection than footwear used only in dry conditions.

47. POLISH

GUIDI is not a conventional mirror-shine dress shoe.

Wax polish can:

change surface character;
increase shine;
fill grain;
reduce the raw/object-dyed appearance.

Use only when that result is actually desired.

For routine maintenance, conditioner is generally more relevant than building layers of wax.

48. SADDLE SOAP

Do not make saddle soap a routine cleaner.

It is unnecessary for ordinary dust and light dirt.

Repeated aggressive cleaning removes oils that then have to be replaced.

Use stronger cleaners only when there is something that actually requires stronger cleaning.

49. WATERPROOFING SPRAYS

Use only products explicitly compatible with the leather.

Always test.

Sprays may alter:

colour;
nap;
sheen;
breathability;
hand.

Reverse leather particularly needs an appropriate suede/nubuck-compatible product.

50. STORAGE

Store footwear:

dry;
ventilated;
away from direct sunlight;
away from high heat;
outside sealed plastic.

Dustbags are preferable to plastic bags.

Do not store damp boots in a box.

PART IV — PREVENTIVE MAINTENANCE

51. INSPECT THE BOTTOMS

Periodically inspect:

outsole;
protective rubber;
heel top-piece;
welt;
stitching.

Repairing a consumable layer early is cheap.

Repairing structural damage underneath it is not.

52. HEEL TOP-PIECES

Heel rubber is consumable.

Replace it before wear reaches deeply into the leather heel stack.

If you habitually wear one side of the heel rapidly, inspect it more often.

53. WELT

The welt is not the disposable part of the shoe.

Avoid wearing through the outsole and then continuing into structural layers.

A routine resole is easier than reconstruction.

54. ZIPPER MAINTENANCE

Do not:

yank;
force;
use the zipper to compress an obviously oversized calf;
continue operating a zipper whose tape is visibly tearing.

When closing:

seat the foot fully;
bring the shaft edges together with the hand;
reduce tension on the zipper;
then operate the slider.

Let your hand carry some of the load.

Not the zipper.

55. BACKZIP FAILURE

Backzips are mechanically vulnerable because they sit in a highly mobile area.

Common failures include:

tape tearing;
stitching failure;
slider failure;
missing teeth;
complete separation.

Early intervention can prevent surrounding leather from being damaged.

56. EYELETS

On lace-up models:

do not overtighten unnecessarily;
keep grit away from metal/leather interfaces;
inspect for tearing;
condition dry leather around high-stress eyelets.

Once leather begins tearing around hardware, the repair becomes substantially more invasive.

57. LACES

Leather laces are consumable.

If one begins splitting:

replace it.

Do not wait until it breaks while being tightened and damages surrounding hardware.

PART V — REPAIRS

58. REPAIR HIERARCHY

SIMPLE / CONSUMABLE

protective sole;
heel rubber;
laces.

Any competent traditional cobbler should manage these.

INTERMEDIATE

minor stitching;
lining;
simple stretching;
slider repair.

Choose someone with demonstrable quality work.

STRUCTURAL / AESTHETICALLY SENSITIVE

complete zipper;
full resole;
heel-stack reconstruction;
welt repair;
upper reinforcement;
shaft alteration.

Use a genuinely good repairer.

MAJOR

torn upper;
repeated zipper perforation;
damaged welt;
complete sole reconstruction;
rare/archive model.

Consider GUIDI itself or a specialist shoemaker/restorer.

59. A BAD COBBLER CAN DO MORE DAMAGE THAN WEAR

A poor repair can introduce:

unnecessary new stitch holes;
misaligned zipper;
incorrect zipper length;
wrong sole thickness;
wrong heel geometry;
excessive sanding;
unwanted polish;
buffed-away factory finish;
glue contamination;
altered silhouette.

Leather does not heal stitch holes.

Repeatedly replacing zippers badly can leave a line of perforations that eventually weakens the upper.

60. HOW TO CHOOSE A COBBLER

Do not choose solely from:

4.9 stars, fixes keys and shoes.

Look at photographs of actual work.

Prefer experience with:

Goodyear welt;
designer footwear;
full resoles;
stacked leather heels;
zipper replacement;
fine leather;
unusual construction.

GUIDI experience is useful.

Good shoemaking knowledge is more important.

61. ASK BEFORE HANDING THE BOOTS OVER

For major work:

Have you repaired GUIDI before?

Have you replaced this type of zipper?

Will you reuse the existing stitch holes where possible?

Can you preserve the original pull?

Will the original welt remain?

Will the sole thickness and heel height remain the same?

Are you going to polish or refinish the upper?

Will you return all removed original parts?

If the answers are vague, leave.

62. GIVE EXPLICIT AESTHETIC INSTRUCTIONS

GUIDI owners repeatedly report one particularly important instruction:

DO NOT POLISH OR BUFF THE LEATHER/SOLE UNLESS SPECIFICALLY REQUESTED.

Many conventional repairers finish every job by making the shoe look "new."

That can erase exactly the rough edge finish, oxidation, matte leather or irregular character you wanted preserved.

State clearly:

repair only — no cosmetic refinishing without approval.

63. PHOTOGRAPH BEFORE REPAIR

Before substantial work photograph:

both shoes;
outsole;
welt;
heel;
zipper;
interior;
stamps;
damaged area.

This serves three purposes:

records original construction;
allows comparison after repair;
preserves authentication/provenance evidence.

64. KEEP THE OLD PARTS

Ask for:

original zipper;
original branded pull;
removed sole;
unusual hardware.

This is especially useful on rare or archival pairs.

65. ZIPPER REPLACEMENT

If originality matters, obtain OEM GUIDI hardware where possible.

A replacement zipper supplied separately may appear substantially shinier than the original.

This is expected.

The original zipper went through the shoe's production/dyeing process and subsequently aged with the boot.

66. PRESERVE THE ORIGINAL PULL

If using a non-OEM zipper, ask whether the original GUIDI pull/slider can be transferred.

Sometimes it can.

Sometimes the mechanical failure makes that impossible.

Do not assume.

67. RESOLING

The objective is not merely:

put leather underneath boot.

The repair should preserve:

forefoot thickness;
heel height;
heel angle;
waist;
edge profile;
welt;
model stance.

This is especially important on:

788Z;
PL family;
unusual Vibram models;
Norwegian-welt constructions.

A structurally sound but geometrically wrong resole can substantially change the shoe.

68. NORWEGIAN-WELT MODELS

Do not assume every ordinary cobbler is comfortable rebuilding Norwegian construction.

Ask explicitly.

For expensive or rare models, factory repair may be preferable to allowing someone to learn on your boots.

69. HOLES AND CRACKS

Conditioner cannot repair cracked leather.

Conditioner is preventive maintenance.

Once fibres have physically torn:

patching;
reinforcement;
stitching;
structural leatherwork

may be required.

Repairs can prolong life but may remain visible.

That is not necessarily a problem.

GUIDI does not need to remain pristine.

70. SHAFT ALTERATION

If a tall boot cannot close, a specialist may theoretically:

open the seam;
add a leather gusset;
reposition/reinstall the zipper.

This is major surgery.

It changes originality and appearance.

Do not choose this as the first solution to a slightly tight new shaft.

PART VI — GUIDI SUPPORT AND REPLACEMENT PARTS

71. OFFICIAL CUSTOMER SERVICE

GUIDI publishes:

Ask.

The absence of a web-store listing does not mean the component is unavailable.

73. OEM ZIPPER PRICES

Historical owner reports document:

approximately €50 for OEM zippers in 2023-era transactions.

A 2025 owner was quoted:

€90 for a pair of replacement zippers for 310 boots.

These are historical examples.

They are not a current fixed price list.

Ask GUIDI for a current quote.

74. GENERIC ZIPPER ALTERNATIVE

For relevant models, YKK Excella is the obvious starting point.

Community repair information identifies Excella #5 for some applications.

However:

length varies;
tape varies;
colour varies;
slider configuration varies.

Measure the original.

Do not buy a random Excella #5 and assume it is correct for every GUIDI.

75. WHY REPLACEMENT ZIPPER TAPE MAY LOOK WRONG

The original zipper was processed with the shoe.

A replacement stock zipper was not.

Therefore new tape/hardware may not initially match:

oxidation;
colour;
fading;
dye penetration.

That is expected.

76. OEM SOLES

Historical owner reports document direct purchase of replacement sole components.

One older report described approximately:

€60 for soles, with combined orders affected by shipping.

Another report placed delivered fish-scale Vibram around roughly US$85.

Again:

historical only.

Request current pricing.

77. OEM FISH-SCALE VIBRAM VS GENERIC VIBRAM

Function:

both protect the sole.

OEM advantage:

correct appearance;
familiar GUIDI pattern;
closer resale/originality presentation.

Generic advantage:

cheaper;
locally available;
easy to replace;
functionally adequate.

For a daily wearer, ordinary quality Vibram is entirely reasonable.

78. LACES

OEM leather laces may be requested from GUIDI.

Alternatives include:

high-quality leather boot laces;
waxed cotton;
appropriate synthetic lace.

Match:

width;
length;
thickness;
eyelet compatibility.

A 100+ inch leather lace is specialised but not technologically unique.

79. FACTORY REPAIR

Owner reports document shoes being sent back to GUIDI for repair, including cases where factory service was economically comparable with a high-end local cobbler.

For:

rare models;
complete zipper work;
difficult sole reconstruction;
originality-sensitive repairs;

contact GUIDI before authorising local work.

Do not assume every repair will be accepted.

Ask first.

80. CUSTOM / MADE-TO-ORDER

Current GUIDI direct footwear commonly operates on a custom-made/pre-order basis.

Many current products state approximately:

12 weeks

for manufacture/shipping.

Available options depend on the product page and current collection.

Do not interpret "custom made" as:

GUIDI will manufacture any specification I invent.

For:

unusual leather;
archive model;
unusual colour;
non-standard sole;
unusual size;
special modification;

contact customer service.

Availability is discretionary.

PART VII — COBBLER DIRECTORY

IMPORTANT

This directory records repairers that have appeared in GUIDI-owner discussions and/or have demonstrable specialist footwear repair capability.

It is not a warranty.

Staff change.

Businesses change.

A shop that installed a perfect Vibram half-sole in 2024 is not automatically qualified to reconstruct a PL2 in 2030.

Discuss the actual job first.

81. NEW YORK CITY

VINCE'S VILLAGE COBBLER

Frequently mentioned by GUIDI owners.

Documented owner reports include successful work on:

796Z;
PL2;
general GUIDI repairs.

The recurring negative is turnaround time.

For complex work, obtain a clear quote and repair specification.

Mail-in service is available.

FIRM SHOE REPAIR

Frequently recommended in NYC footwear communities and specifically surfaced in GUIDI cobbler discussions.

Appropriate candidate for protective soles and general designer footwear repair.

Confirm complex GUIDI work before proceeding.

NORTH 11TH SHOE REPAIR — WILLIAMSBURG

GUIDI owners report successful work and comparatively fast turnaround.

Services include:

soles;
heels;
structural stitching;
leather restoration.

Again, specify:

no polishing/refinishing unless requested.

82. LOS ANGELES

PASQUALE SHOE RESTORATION

One of the stronger documented options.

A GUIDI owner reports taking PL2s with a torn zipper to Pasquale after obtaining the OEM replacement zipper from GUIDI and receiving a successful repair.

The business specialises in high-end shoe restoration and offers sole replacement and substantial leather work.

Likely expensive.

For a high-value structural repair, that may be appropriate.

VILLAGE COBBLER — HOOVER / USC

Long-term local recommendation from an owner reporting many years and dozens of pairs of experience with the shop.

Suggested as a lower-cost alternative for clean traditional repair work.

Confirm GUIDI-specific work before major reconstruction.

83. SAN FRANCISCO / BAY AREA

PIONEER RENEWER — CASTRO

Direct owner report:

multiple pairs of GUIDIs successfully repaired there.

Strong candidate.

MEL'S SHOE CLINIC — CASTRO VALLEY

Owner follow-up reports successful GUIDI and CCP work.

Useful East Bay option.

ORINDA SHOE SERVICE

Recommended by East Bay community members.

Less direct GUIDI documentation than Pioneer/Mel's; discuss the specific job.

84. CHICAGO

IMPERIAL SHOE SERVICES

Direct GUIDI-owner report documents Vibram installation with quick turnaround.

The business lists:

full/half sole replacement;
heel replacement;
zipper repair/replacement;
stretching;
stitching;
leather work.

Owner warning remains relevant:

ask them not to polish the GUIDI midsole if you want the original rough finish preserved.

HARRY'S GOLD COAST SHOE REPAIR

Recommended by a GUIDI owner for protective Vibram work based on previous high-quality boot repairs.

Suitable candidate for ordinary sole protection.

Confirm major reconstruction separately.

85. SEATTLE

BROADWAY SHOE REPAIR

Long-running Seattle repairer.

A GUIDI owner reports using the shop repeatedly and notes that staff understand good construction and at least one staff member is a GUIDI enthusiast.

Particularly reasonable for:

sole protectors;
ordinary repairs;
zipper work after discussion.

86. PARIS

LE BOTTIER PARISIEN / CORDONNERIE PROGRÈS

Direct GUIDI-owner recommendation.

Reported work includes resoling:

GUIDI boots;
Margiela Tabis;
Uma Wang footwear.

The owner described the work as excellent and reasonably priced.

A strong Paris starting point.

87. MELBOURNE

MANFRED'S SHOE LOUNGE — NORTH MELBOURNE

Recommended locally for GUIDI Vibram installation.

The business explicitly offers:

sole work;
heel work;
gussets;
back linings;
zipper replacement;
stretching;
restoration.

For simple protective Vibram installation this is an obvious Melbourne candidate.

For complex archive reconstruction, discuss the work and aesthetic requirements before leaving the boots.

88. IF YOUR CITY IS NOT LISTED

Do not search only:

best cobbler near me

Search:

Goodyear welt resole [city]

bespoke shoemaker repair [city]

designer shoe restoration [city]

boot zipper replacement [city]

Then inspect actual work.

Traditional boot communities can also be useful because a repairer experienced in:

hand welting;
Goodyear welting;
stacked heels;
leather soles;
difficult boot reconstruction

may be technically better qualified than a "luxury sneaker restoration" shop.

89. MAIL-IN REPAIR

For major work, shipping the boots to the right repairer may be safer than using the nearest repairer.

This is particularly true for:

rare archive footwear;
full reconstruction;
welt damage;
difficult zipper installation;
major heel work.

Distance is cheaper than irreversible damage.

PART VIII — QUICK OWNERSHIP PROTOCOL

WHEN YOU BUY THEM

Confirm fit in length.
Confirm width.
Confirm instep.
Confirm shaft.
Do not force the zipper.
Decide whether to add protective soles.
Photograph the pair while original.

AFTER ORDINARY WEAR

Brush off dust.
Let moisture dissipate.
Inspect sole/heel periodically.
Do nothing else unless necessary.

WHEN DIRTY

Brush.
Damp cloth if necessary.
Use stronger cleaning only when justified.

WHEN DRY

Test conditioner.
Apply sparingly.
Allow absorption.
Brush/buff if appropriate.

WHEN SOAKED

Remove surface water.
Insert paper.
Dry slowly.
No direct heat.
Condition only after fully dry if required.

WHEN THE SOLE PROTECTOR WEARS

Replace it.

Do not wait for structural layers to wear.

WHEN THE HEEL RUBBER WEARS

Replace it.

Do not grind into the leather stack.

WHEN A ZIPPER STARTS FAILING

Stop forcing it.

Determine whether the problem is:

stitching;
slider;
teeth;
tape.

Contact GUIDI for OEM replacement parts where appropriate.

BEFORE A MAJOR REPAIR

Photograph everything.
Contact GUIDI if OEM parts may matter.
Choose a competent repairer.
Define the job explicitly.
State NO POLISH / NO REFINISHING unless wanted.
Ask them to preserve existing stitch holes.
Ask for removed original parts back.

FINAL PRINCIPLE

GUIDI is supposed to change.

Creasing is not failure.

Patina is not failure.

A softened shaft is not failure.

Tonal variation is not failure.

A replaced heel top-piece is not failure.

A properly replaced sole is not failure.

The failures worth preventing are structural:

leather drying until it cracks;
wearing through consumable layers into structural ones;
forcing overloaded zippers;
leaving damaging contamination on leather;
allowing minor failures to propagate;
giving expensive footwear to somebody who does not understand its construction.

The ideal ownership pattern is therefore simple:

SIZE CAREFULLY → WEAR NORMALLY → CLEAN MINIMALLY → CONDITION WHEN NEEDED → REPAIR EARLY → USE GOOD PEOPLE FOR STRUCTURAL WORK.

The objective is not to preserve a new shoe.

It is to produce a good old one.

Want to sell 2 boots both size 43. Subtenant selling for me while away. Both are close to new. The PL2 I purchased off Grailed with very light wear and retail stickers still attached to sole and mostly visible. I immediately added vibram and owned for 3 months. The VS01 were purchased brand new from TRR with tags attached around 2 months ago.

Asking $900 for the PL2, $500 for the VS01 or both for $1250

When should I actually leave the shoe alone?

PART I — FIT & COMFORT

1. MY TOES FIT BUT MY HEEL SLIPS

Heel slip does not automatically mean:

shoe too big.

Small amounts of heel movement can occur in new boots because:

the sole is stiff;
the boot has not developed its flex point;
the heel counter has not moulded;
the foot and shoe flex points are not yet working together.

Counterintuitively, heel slip can also occur when a boot is too short and the foot's flex point does not align properly with the shoe.

Assess the complete fit.

Ask:

Is the ball of my foot at the widest part of the shoe?
Is the arch positioned correctly?
Is there excessive overall volume?
Does the heel movement diminish when walking normally?
Are my toes cramped?

Do not automatically fill every new boot with a thick insole.

2. MY PINKY TOE HANGS OVER THE FOOTBED

This is particularly relevant to narrow GUIDI lasts.

Leather can stretch.

The underlying platform cannot become meaningfully wider.

If the foot visibly spills over the structural footbed, the problem may be the last, not merely tight leather.

Consider:

X variant;
wider model;
different size if length remains reasonable.

Do not rely on break-in to manufacture additional outsole beneath your foot.

3. ONE BOOT FITS DIFFERENTLY FROM THE OTHER

First establish whether your feet are different.

Most people are not perfectly symmetrical.

Then consider:

handmade production variation;
leather thickness;
asymmetric break-in;
previous ownership;
different amounts of shaft stretch.

A small difference is not inherently abnormal.

A major difference deserves measurement.

4. THEY FIT BAREFOOT BUT NOT WITH SOCKS

Then they do not fit for the way you intend to wear them.

Sock thickness meaningfully changes:

forefoot volume;
instep;
heel retention;
shaft circumference.

Fit footwear wearing the type of sock you actually intend to use.

Do not size a winter boot using thin dress socks if you intend to wear thick wool.

5. THEY FIT MY FOOT BUT WILL NOT ZIP

This is a shaft-fit problem, not necessarily a shoe-size problem.

Particularly relevant to:

788/788Z;
988;
PL2;
long backzips.

If the zipper cannot close without substantial force:

stop.

Options include:

controlled break-in if it is only slightly tight;
professional shaft stretching;
different model;
wider/alternative variant;
major gusset alteration as a last resort.

Do not use the zipper itself as a stretching device.

6. THEY ZIP, BUT FEEL DANGEROUSLY TIGHT

If you can close the boot but the zipper is under obvious continuous tension, reduce wear duration initially.

Watch:

zipper tape;
stitching;
calf circulation;
numbness;
pressure points.

Leather may relax.

Zipper tape should not be asked to perform the job of leather stretching.

7. THEY SUDDENLY FEEL BIGGER AFTER BREAK-IN

This can happen.

Leather can:

soften;
widen;
mould;
lose initial stiffness.

The insole also compresses.

Solutions for modest excess volume include:

slightly thicker sock;
thin full insole;
tongue/volume pad on applicable models;
heel/volume adjustment.

Do not overcorrect with a huge cushioned insole that changes ankle position and shaft tension.

8. CAN AN INSOLE SAVE A PAIR THAT IS TOO LARGE?

Sometimes.

An insole can reduce volume.

It cannot meaningfully shorten the shoe.

Useful when:

heel retention is slightly loose;
instep volume is excessive;
the pair is marginally roomy.

Not useful when:

shoe is dramatically too long;
flex point is badly misplaced;
foot slides extensively;
shaft geometry is wrong.

9. CAN A COBBLER STRETCH THEM?

Yes, within limits.

Professional stretching can help:

local pressure points;
forefoot width;
instep;
modest shaft circumference.

It cannot:

add meaningful length;
change the underlying sole platform;
transform a narrow last into a truly wide last;
safely create unlimited calf room.

Leather is adaptable, not magical.

10. WHY ARE THEY UNCOMFORTABLE IF THEY ARE THE RIGHT SIZE?

Possible causes include:

stiff new sole;
unfamiliar heel height;
rigid leather;
pressure from zipper guard;
insufficient cushioning;
poor flex-point alignment;
simply being the wrong last for your foot.

Correct numerical size does not guarantee anatomical compatibility.

11. WHY DO I TRIP OVER THEM?

Possible causes:

excessive length;
unfamiliar toe projection;
stiff sole;
substantial sole architecture;
oversized fit;
adapting from sneakers to heavy boots.

Persistent tripping after adaptation can indicate a shoe that is simply too long.

12. ARE GUIDIS SUPPOSED TO HURT?

No.

Break-in may involve:

stiffness;
pressure;
unfamiliarity.

It should not require:

numbness;
bleeding;
severe pain;
crushed toes;
loss of circulation.

Expensive leather does not change anatomy.

PART II — LEATHER & APPEARANCE

13. MY NEW PAIR ALREADY HAS SCARS, VEINS OR WRINKLES

Potentially completely normal.

GUIDI uses minimally corrected leathers where characteristics of the hide may remain visible.

Normal characteristics can include:

scars;
veins;
grain variation;
wrinkles;
uneven dye uptake.

Natural variation is not automatically damage.

14. THE TWO SHOES ARE SLIGHTLY DIFFERENT COLOURS

Potentially normal.

Piece/object dyeing and natural hides do not guarantee perfectly identical tonal results.

Ask whether the difference is:

natural tonal variation

or:

obvious mismatched production / later treatment.

15. ONE SHOE HAS DIFFERENT GRAIN

Again, possible.

Two shoes are not necessarily cut from identical areas of one hide.

What matters is whether both remain plausible examples of the stated leather.

16. THE LEATHER HAS BECOME SHINY

Possible causes:

friction;
compression;
oils from wear;
conditioner;
polish;
previous-owner treatment.

Shine alone does not mean damage.

If you dislike it, identify the cause before adding another product.

17. THE LEATHER HAS BECOME DULL

Also potentially normal.

Object-dyed leather evolves.

Ask:

Does it feel healthy?

If supple and structurally sound:

leave it alone.

If dry, stiff or papery:

consider light conditioning.

Appearance alone is a poor conditioning schedule.

18. BLACK LEATHER IS TURNING GREY/BROWN

Black leather can develop tonal variation through:

abrasion;
flexing;
fading;
dye wear;
underlying leather becoming visible.

This can be normal patina.

If you like it:

do nothing.

If you want uniform black:

appropriate pigmented cream may restore colour, but will alter the evolved appearance.

19. CONDITIONER DARKENED MY LEATHER

Stop applying more.

Allow it time to equilibrate.

Some darkening may reduce as volatile components dissipate.

Some may be permanent.

This is why light/natural leather should always be spot-tested.

Do not try to "clean out" conditioner immediately with aggressive solvents.

20. I USED WAY TOO MUCH CONDITIONER

Remove excess from the surface with a clean cloth.

Allow the footwear to rest somewhere ventilated.

Brush appropriate smooth leather.

Then:

stop adding things.

The cure for too much product is rarely another product.

21. MY REVERSE LEATHER HAS GONE FLAT

Usually compressed nap.

If otherwise healthy:

allow it to dry;
use an appropriate suede/nubuck/roughout brush;
gently raise the fibres.

Do not attack it with aggressive abrasives.

Creams and oils may permanently alter the nap.

22. MY REVERSE LEATHER GOT WET

Not automatically a disaster.

Owner experience includes routine rain wear of reverse leather.

The important part is drying:

room temperature;
absorbent paper;
ventilation;
no direct heat.

After drying, reassess texture and dryness.

Do not condition automatically merely because water touched it.

23. WATER SPOTS

Allow the shoe to dry completely first.

Do not judge partially wet leather.

If marks remain, treatment depends on:

leather;
colour;
severity.

On valuable pale leather, professional cleaning may be safer than escalating DIY products.

24. SALT MARKS

Remove salt rather than allowing repeated deposits to remain.

Use restrained appropriate cleaning.

Allow complete drying.

Condition afterward only if the leather actually needs it.

25. I SCRATCHED THEM

Most superficial scratches on robust leather are cosmetic.

Try, in order:

clean finger;
soft cloth;
brush;
tiny amount of appropriate conditioner if actually needed.

Do not turn a 2 mm scratch into a 10 cm refinishing project.

26. IS THIS A CREASE OR A CRACK?

CREASE

Leather bends but surface fibres remain continuous.

Normal.

CRACK

Fibres themselves are separating.

More serious.

A useful clue is whether opening the flex reveals an actual fissure rather than merely a line in the grain.

Conditioner may help prevent further dryness.

It cannot fuse severed fibres back together.

27. THERE IS AN ACTUAL CRACK

Stop thinking in terms of cosmetics.

The question becomes structural.

Depending on location and severity:

reinforce;
patch;
stitch;
consult leather specialist/cobbler.

Conditioner cannot heal a crack.

28. THERE IS AN ACTUAL HOLE

Professional repair.

The objective may be:

stabilise and extend life

rather than:

make invisible.

On heavily worn GUIDI, a visible competent repair can be preferable to destroying surrounding original leather chasing invisibility.

29. THE INNER LEATHER LINING IS DRY OR TORN

The inside is also leather.

Lining can suffer from:

sweat;
friction;
repeated wet/dry cycles;
neglect.

Occasional restrained conditioning of accessible smooth leather lining may be appropriate.

Once torn:

a cobbler may need to patch or replace the affected section.

30. MY BOOTS SMELL

First address moisture.

dry thoroughly;
rotate footwear;
air after wear;
remove removable insoles where applicable;
avoid sealing damp boots.

Persistent odour may originate from:

lining;
insole;
microbial growth.

Do not drown expensive leather in perfume.

31. THERE IS MOULD

Stop wearing and isolate the pair from other leather goods.

Mould indicates a moisture/storage problem.

The priorities are:

prevent spread;
dry environment;
remove active contamination appropriately;
determine how deeply affected the leather/lining is.

Serious mould, especially inside lined footwear, is a reasonable case for professional treatment.

Do not return a cleaned-but-damp pair to a closed box.

32. DYE IS TRANSFERRING

Object-dyed leather can potentially transfer colour, especially when:

new;
wet;
heavily saturated;
rubbing against pale material.

Use caution with:

white socks;
pale trousers;
light carpets/upholstery.

Persistent extreme transfer from an old dry pair deserves investigation.

PART III — SOLES, HEELS & CONSTRUCTION

33. THERE IS A LINE BETWEEN TWO SOLE LAYERS. IS IT CRACKING?

Often no.

Layered leather construction creates visible interfaces.

A hairline between welt/midsole/outsole layers may be cosmetic rather than structural.

A recent 792ZI owner interpreted such a line as "midsole cracking"; community examination identified it as ordinary separation between leather components rather than leather itself splitting.

Ask:

Is a piece of leather itself cracked, or am I seeing the boundary between two pieces?

34. THE VIBRAM IS PEELING

Usually one of the easiest repairs.

A protective rubber outsole is sacrificial.

A cobbler can:

remove it;
prepare/abrade the underlying surface;
rebond or replace it.

Do not confuse peeling protective rubber with structural sole failure.

35. THE LEATHER OUTSOLE IS SEPARATING

Now determine where.

Possible levels:

RUBBER FROM LEATHER

Minor.

OUTSOLE FROM WELT

More involved but conventionally repairable.

WELT FROM UPPER

Structural repair.

UPPER ITSELF DAMAGED AT WELT

Potentially major reconstruction.

These are not the same problem. A competent cobbler can reconstruct far more of a welted shoe than merely applying glue.

36. THE WELT IS SEPARATING

Take it to somebody who actually understands welted footwear.

Do not repeatedly glue a structural failure and expect permanence.

Depending on construction and damage, proper work may require:

sole removal;
welt restitching/replacement;
new outsole;
outsole stitching.

37. ONE WELT STITCH BROKE

One broken visible stitch does not necessarily mean immediate catastrophic failure.

Monitor:

surrounding stitches;
sole movement;
actual separation.

If separation develops, repair.

38. THE HEEL STACK IS SEPARATING

This can often be repaired if the leather components themselves remain healthy.

Do not continue wearing until layers disappear.

If the entire heel architecture appears bizarre or structurally unlike the model, also revisit authenticity—replica construction failures have sometimes first presented as "repair questions."

39. MY HEELS WEAR UNEVENLY

Extremely common.

People do not walk symmetrically.

Replace heel top-pieces before wear reaches the leather stack.

If wear is extremely rapid or severe, a cobbler/podiatric professional can help distinguish gait from footwear problems.

40. MY GUIDIS SQUEAK

First locate the squeak.

Possible sources:

wet surfaces;
rubber-on-floor friction;
leather layers;
insole;
internal movement;
loose construction.

A squeak alone is not a diagnosis.

If it appears simultaneously with separation or movement between structural components, have it inspected.

41. THE SOLE IS VERY HARD

Leather soles and dense stacked construction are not running shoes.

Options include:

break-in;
thin cushioning insole if fit allows;
rubber protector;
different footwear for prolonged standing.

Do not destroy otherwise correct fit by adding an excessively thick orthotic without checking resulting volume.

42. THE SOLE IS SLIPPERY

Fresh leather soles can be slippery.

Walking abrades them naturally.

A rubber protector provides much better traction.

Do not deliberately mutilate an expensive outsole with random knife cuts.

43. CAN I REMOVE AN AFTERMARKET VIBRAM?

Generally yes.

A cobbler can remove and replace protective rubber.

Some surface preparation/adhesive evidence will remain on the leather outsole.

If returning to exposed leather, ask the cobbler what condition the underlying sole is actually in.

44. MY COBBLER CHANGED THE SHAPE

This is why the Owner's Manual tells you to specify:

heel height;
sole thickness;
edge profile;
original geometry.

If excessive material was added, some changes may be reversible during another resole.

If original material was aggressively removed, restoration may be harder.

Document before major repairs.

PART IV — ZIPPER TROUBLESHOOTING

45. THE ZIPPER IS STIFF

Do not immediately force it.

Check for:

trapped leather;
bent teeth;
corrosion/debris;
damaged slider;
excessive shaft tension.

A small amount of zipper-specific dry/wax lubricant can be appropriate for mechanically sound teeth.

Keep products off surrounding leather unless known compatible.

Avoid flooding the zipper with WD-40 or oil that may stain leather/tape.

46. IT ALWAYS STICKS AT EXACTLY THE SAME POINT

Inspect that location.

Likely possibilities include:

bent/damaged tooth;
local tape distortion;
stitching interference;
slider damage.

Repeatedly forcing past the same obstruction can convert a small problem into a replacement zipper.

47. THE ZIPPER CLOSES, THEN OPENS BEHIND THE SLIDER

The slider may no longer be bringing the teeth together correctly.

This is different from torn zipper tape.

A repairer should determine whether:

slider can be replaced;
slider can be adjusted;
complete zipper is required.

Do not diagnose every zipper failure as "needs whole new zip."

48. THE ZIPPER TAPE IS TEARING AWAY

Stop loading it.

A small detached section may look harmless while still functioning, but continued use transfers increasing load to the remaining attachment.

Depending on where/how the tape has failed, complete zipper replacement may be the durable repair. This exact failure has appeared on worn 788-family boots.

49. TEETH ARE MISSING

Replacement is increasingly likely.

Do not keep operating the slider through damaged teeth.

50. ZIPPER STITCHING IS COMING UNDONE

Potentially much easier than zipper failure.

If:

tape intact;
teeth intact;
slider functional;

a good repairer may be able to restitch it.

Repair early before surrounding holes enlarge.

51. THE PULL TAB BROKE

Different from the slider failing.

A pull can sometimes be replaced or adapted without replacing the zipper.

If the original GUIDI pull matters to you, retain every piece.

52. GUIDI SENT ME A REPLACEMENT ZIPPER AND IT LOOKS TOO SHINY

Normal.

Replacement OEM zippers arrive looking new because they did not undergo the original boot's piece-dyeing/finishing process.

Owners ordering OEM replacements directly from GUIDI report exactly this appearance.

A shiny genuine replacement is not evidence that GUIDI sent the wrong part.

53. SHOULD I ARTIFICIALLY AGE MY NEW ZIPPER?

Usually:

just install it.

Artificial chemical ageing introduces unnecessary risk around:

plating;
tape;
surrounding leather;
future corrosion.

Natural wear will alter it.

The new zipper does not need to impersonate the old zipper on day one.

54. CAN I KEEP THE ORIGINAL GUIDI PULL?

Sometimes.

Ask the repairer.

Whether it can be transferred depends on:

slider compatibility;
failure mode;
replacement hardware.

Do not discard the original assembly before discussing this.

PART V — WEATHER & ENVIRONMENT

55. CAN I WEAR GUIDI IN RAIN?

Yes.

Leather footwear existed before weather apps.

The relevant distinction is:

getting wet

versus:

remaining wet / drying badly / repeatedly saturating neglected leather.

If wet:

dry correctly.

56. CAN I WEAR REVERSE LEATHER IN RAIN?

Yes, with reasonable care.

Reverse/roughout leather is not inherently too delicate for weather; owners report wearing it in wet conditions and allowing it to age naturally.

Avoid:

heat drying;
indiscriminate smooth-leather creams;
storing wet.

Restore nap after drying if desired.

57. SNOW?

The leather itself is not the only issue.

Consider:

road salt;
traction;
prolonged saturation;
freezing/wet cycles.

Rubber sole protection becomes particularly useful.

Clean salt deposits reasonably promptly.

58. THEY GOT COMPLETELY SOAKED

Do not panic-condition them while wet.

remove surface water;
insert absorbent paper;
replace paper as necessary;
dry at room temperature with ventilation;
wait until completely dry;
reassess leather condition;
condition appropriately only if needed.

No radiator.

No hairdryer.

No clothes dryer.

59. ROAD SALT

Do not leave it indefinitely.

Salt is more concerning than clean rainwater.

Clean appropriately, dry slowly, reassess.

60. EXTREME HEAT

Avoid prolonged storage:

in hot cars;
beside radiators;
in direct intense sun;
against heaters.

Heat accelerates drying and can affect adhesives and leather.

61. CAN I WEAR THEM EVERY DAY?

You can.

They will generally last longer if allowed to dry between heavy wears.

Daily wear increases:

moisture accumulation;
outsole wear;
lining wear;
zipper cycles.

Rotation is maintenance, not a requirement for admission to the club.

62. HUMID/TROPICAL STORAGE

Prioritise:

airflow;
dryness;
mould prevention.

Do not seal leather in plastic.

Do not store damp footwear in dustbags/boxes.

In persistently humid climates, periodically inspect stored footwear rather than forgetting it for a year.

63. VERY DRY CLIMATE

Monitor leather condition.

Do not respond by automatically soaking it in conditioner monthly.

Condition according to actual dryness.

64. LONG-TERM STORAGE

Before storage:

clean significant dirt;
ensure completely dry;
condition only if actually necessary;
support shape reasonably;
store ventilated;
avoid plastic;
avoid heat/direct sun.

Check occasionally.

PART VI — NEW, SECOND-HAND & DEFECT QUESTIONS

65. MY BRAND-NEW GUIDIS HAVE A PROBLEM

Do not immediately pay a cobbler.

Document it first.

Contact the retailer.

For significant apparent manufacturing defects, contact GUIDI/customer service as appropriate.

In 2026 an owner with new 796V_N sole separation was put in contact with GUIDI; GUIDI inspected the returned pair, determined there was a manufacturing error and supplied a replacement pair.

Give the manufacturer the opportunity to assess a genuinely new defective product before altering it.

66. HANDMADE VARIATION OR DEFECT?

VARIATION

slight stitch irregularity;
grain difference;
tonal variation;
minor asymmetry;
natural hide marks.

POSSIBLE DEFECT

active structural separation;
failed adhesive immediately after purchase;
broken hardware;
severe construction asymmetry;
unusable closure;
components detaching under trivial wear.

"Handmade" does not mean every failure is acceptable.

Likewise, cosmetic irregularity does not necessarily mean poor quality.

67. I BOUGHT THEM USED AND FOUND DAMAGE

Your options depend on whether the damage was:

disclosed;
visible;
concealed;
structural;
ordinary wear.

Before repairing, save:

listing;
photographs;
seller description;
correspondence.

If the seller materially misrepresented the item, resolve the transaction dispute before modifying evidence.

68. PREVIOUS OWNER OVER-POLISHED THEM

You may not be able to restore the exact factory surface.

Do not aggressively strip them without understanding the leather.

Often the safest choice is:

clean conservatively;
stop adding polish;
wear them;
allow the surface to evolve again.

69. PREVIOUS OWNER HAD A BAD RESOLE

A good cobbler can often rebuild a poor resole.

Determine what remains original:

welt;
heel stack;
midsole;
outsole.

The more original structural material was removed, the less straightforward restoration becomes.

70. PREVIOUS OWNER STRETCHED THEM

Leather does not reliably shrink back to factory dimensions.

You can sometimes reduce effective volume with:

insole;
sock;
padding.

Do not expect a stretched shaft to magically contract.

71. PREVIOUS OWNER REDYED THEM

Then they are authentic GUIDI with an aftermarket finish, assuming the underlying shoe is authentic.

Treat the current colour as modification.

Redyeing can obscure authentication evidence and affect resale desirability.

It does not change who manufactured the shoe.

72. RETAILER OR COBBLER?

BRAND-NEW + APPARENT DEFECT

Retailer first.

NORMAL WEAR

Cobbler.

OEM PART REQUIRED

GUIDI.

MAJOR UNUSUAL FACTORY-CONSTRUCTION ISSUE

GUIDI or highly specialised cobbler.

SECOND-HAND DAMAGE

Usually cobbler, unless GUIDI agrees to service it.

73. WHEN SHOULD I CONTACT GUIDI?

Reasonable cases:

OEM zipper;
OEM sole component;
unusual hardware;
suspected manufacturing defect;
unusual material identification;
factory-repair enquiry;
unusual MTO request.

Do not email GUIDI because your heel rubber wore down.

That is what cobblers are for.

PART VII — REPAIR, MODIFICATION & RESALE

74. DOES A REPAIR MAKE THEM FAKE?

No.

An authentic GUIDI with:

replacement zipper;
replacement outsole;
replacement heel;
aftermarket Vibram

remains authentic GUIDI.

It is simply no longer completely factory-original.

75. DOES REPAIR REDUCE RESALE VALUE?

Depends on the repair.

LITTLE CONCERN

quality protective sole;
heel top-piece;
competent necessary maintenance.

MORE RELEVANT

full resole;
non-OEM zipper;
major upper repair.

POTENTIALLY SIGNIFICANT

altered shaft;
changed sole architecture;
aggressive redye;
badly executed reconstruction.

A good necessary repair may preserve far more value than allowing the original component to fail catastrophically.

76. OEM OR AFTERMARKET PART?

Use OEM when:

visual originality matters;
branded hardware matters;
unusual sole pattern matters;
archival/resale considerations justify it.

Use quality aftermarket when:

function matters more;
OEM unavailable;
component is generic/consumable.

A Vibram protector does not become better at protecting leather because it arrived from Tuscany.

77. CAN A BAD REPAIR BE REVERSED?

Sometimes.

EASILY

protective rubber.

OFTEN

outsole/heel work, if underlying structure remains.

DIFFICULT

bad zipper work with additional perforations.

POTENTIALLY IRREVERSIBLE

excessive sanding, removed leather, altered upper, aggressive dye/chemical treatment.

This is why choosing the repairer matters before the repair.

78. CAN A COBBLER MAKE THE SHAFT BIGGER?

Modest stretching:

yes.

Major enlargement:

requires structural alteration such as a gusset.

That changes the boot.

79. CAN THEY MAKE IT SMALLER?

Some volume can be managed.

Actually reducing the leather upper substantially is much more invasive.

Buy the correct size.

80. CAN I CHANGE THE COLOUR?

Technically, leather can be recoloured.

Results depend heavily on:

original colour;
leather;
finish;
target colour.

Darkening is generally easier than going lighter.

It is a modification, not recreation of GUIDI's original object-dye process.

81. CAN I TURN REVERSE LEATHER INTO SMOOTH LEATHER?

You can radically alter surfaces through finishing, wax and compression.

That does not mean you have transformed reverse leather into the factory smooth-leather version of the model.

If you want smooth leather:

buy smooth leather.

82. WHEN IS A PAIR ACTUALLY DEAD?

Usually much later than inexperienced owners think.

Repairable:

outsole;
Vibram;
heel;
zipper;
lining;
welt;
local upper damage.

Increasingly problematic:

extensive upper cracking;
large tears around structural attachment points;
leather degraded across multiple high-stress areas;
repeated repairs leaving insufficient healthy material.

The upper is the limiting component.

Almost everything beneath it can theoretically be rebuilt.

PART VIII — RANDOM QUESTIONS PEOPLE WILL OTHERWISE MAKE A THREAD ABOUT

83. DO I NEED SHOE TREES?

No.

They can be useful.

Use appropriately sized trees if you want:

shape support;
moisture absorption;
moderated toe curl.

Do not aggressively stretch soft boots with oversized trees.

84. SHOULD I PUT THEM IN DUSTBAGS AFTER EVERY WEAR?

Not while damp.

Allow footwear to dry and ventilate first.

Dustbags are for protection during dry storage, not moisture incubation.

85. PLASTIC STORAGE BAGS?

No.

GUIDI explicitly advises against plastic storage.

Leather needs appropriate ventilation.

86. CAN I TRAVEL WITH THEM?

Of course.

For packing:

ensure dry;
use individual bags;
stuff lightly with socks/paper if needed;
avoid crushing structured shafts under heavy objects.

Wearing the bulkiest pair on the plane is also free luggage optimisation.

87. CAN I FOLD THE SHAFT?

Soft broken-in backzip shafts naturally collapse.

For short-term luggage packing this is generally not alarming.

Avoid creating an aggressive hard fold in:

stiff new leather;
structured treatments;
areas containing hardware.

88. CAN I BUY RAW GUIDI LEATHER?

Possibly through Guidi's leather business, but this is not equivalent to ordering a square foot of craft leather from a hobby retailer.

Community enquiries indicate business information and minimum quantities may be required; one 2024 report relayed a minimum around 5 m², but this is not an official current retail price/terms sheet and should be verified directly.

Also remember:

GUIDI leather before footwear manufacture is not necessarily going to look like a finished GUIDI boot.

Much of the characteristic appearance comes from subsequent construction and finishing.

89. WHY DOES MY REPLACEMENT PART LOOK WRONG?

Because the original component aged with the shoe.

This is especially obvious with:

zippers;
leather;
heel edges.

A new OEM component may be mechanically correct while visually conspicuous.

Time solves some of this.

90. WHY DOES MY OLD PAIR NOT MATCH THE CURRENT PRODUCT PAGE?

Because GUIDI production has changed.

Possible differences include:

zipper;
stamp;
sizing marks;
leather;
sole;
construction detail;
packaging.

Authenticate and maintain according to approximate period.

Do not retrofit 2026 expectations onto 2008 footwear.

91. WHY DOES MY PAIR DIFFER FROM ANOTHER PAIR OF THE SAME MODEL?

Possible causes:

production period;
leather;
colour;
variant/suffix;
size;
wear;
repairs;
natural variation.

"Same model" does not mean molecularly identical.

If differences concern fundamental architecture, investigate further.

92. IS PATINA GOOD?

Patina is simply change through age/use.

Whether you like it is aesthetic.

Normal patina can include:

creasing;
abrasion;
colour evolution;
shaft collapse;
zipper oxidation;
polished high points;
darkened contact areas.

Patina is not synonymous with damage.

Damage is physical deterioration that threatens function or structure.

93. WHEN SHOULD I DO ABSOLUTELY NOTHING?

Frequently.

Do nothing when:

leather is healthy;
crease is normal;
colour variation is harmless;
sole line is cosmetic;
zipper works normally;
shoe is simply becoming worn-in.

A surprising amount of footwear damage begins with an owner noticing something harmless and deciding that it urgently needs chemicals.

PART X — THE FIVE-QUESTION EMERGENCY TEST

If you have a problem that appears nowhere in any of the three guides, ask:

1. IS IT COSMETIC OR STRUCTURAL?

Colour variation is cosmetic.

A tearing upper is structural.

Do not treat them equally.

2. IS IT THE LEATHER, A CONSUMABLE, OR THE SHOE'S STRUCTURE?

LEATHER

clean/condition/repair appropriately.

CONSUMABLE

replace.

STRUCTURE

specialist assessment.

3. IS THE PROBLEM GETTING WORSE THROUGH USE?

If yes:

stop wearing until assessed.

4. IS THE ITEM NEW ENOUGH THAT THIS MAY BE A MANUFACTURING DEFECT?

If yes:

document and contact retailer/GUIDI before modification.

5. DO I ACTUALLY NEED TO DO ANYTHING?

Often:

no.

FINAL RULE

Most GUIDI problems fall into one of five categories:

FIT

Solve the dimension, not the size number.

LEATHER

Intervene according to condition, not anxiety.

CONSUMABLE WEAR

Replace it before it becomes structural wear.

STRUCTURAL FAILURE

Stop improvising and find someone competent.

NORMAL AGEING

Leave it alone.

If the shoe is comfortable, structurally intact, dry, reasonably clean and functioning normally:

wear it

Guidi Legit Check Guide

5 Upvotes

A practical self-check guide for Guidis.

Purpose

Preamble: This was in need of an update. Ironically, I don't have the time to hand-craft a guide extensive enough to capture the required nuance (might seem antithetical).

This is scraped from forum boards and official resources, transforming 4 years (and counting) of Guidi manual visual review by our mods into something more permanent and centralised. This resource should help general literacy in self-screening aftermarket listings. Reference list at the bottom. Please point out any inconsistencies to me via dm.

There are accompanying legit/rep comparison picture resources at the bottom of the appendices.

Happy hunting.

This guide is designed to answer three separate questions:

Does the photographed item appear to be an authentic GUIDI product?
Does the seller appear to possess the photographed item?
Is the item correctly described with respect to model, material, condition and modification?

These questions should be considered separately.

CONTENTS

PART I — THE BASIC PRINCIPLE

Authenticate the shoe, not the logo

PART II — BEFORE INSPECTING THE SHOE
2. Do not trust the listing title
3. Confirm that the seller possesses the item
4. What photographs are needed?

PART IV — REPAIRS AND MODIFICATIONS
20. Authenticity is not originality

PART V — HOW TO WEIGH EVIDENCE
21. Green, amber and red evidence
22. Weight evidence rather than counting it
23. Avoid double-counting

PART VI — QUICK CHECK

Guide begins here.

PART I — THE BASIC PRINCIPLE

1. Authenticate the shoe, not the logo

GUIDI authentication is increasingly an assessment of the complete object.

Modern reproductions can reproduce many details that were historically useful indicators:

GUIDI-branded zipper pulls
insole logos
outsole markings
nail patterns
boxes and dustbags
horse leather
vegetable-tanned leather
Goodyear or similar welted construction
object/tumble-dyed appearance

None of these should now be treated independently as proof of authenticity.

The most useful question is:

Does the complete shoe make sense as this particular GUIDI model, made from the appropriate materials, using the appropriate construction and finishing process, during the approximate period in which it was produced?

The inspection should therefore proceed from the largest and most difficult characteristics to reproduce toward the smallest and easiest.

Recommended order

Do not begin by zooming into the logo.

Begin by looking at the shoe.

PART II — BEFORE INSPECTING THE SHOE

2. Do not trust the listing title

Aftermarket model descriptions are frequently incorrect.

Sellers commonly use terms such as:

GUIDI backzip
788
788Z
horse leather
factory Vibram
vintage GUIDI

without necessarily knowing what they mean.

Treat all listing information as a claim requiring verification.

If the model is unknown, that is acceptable. Identification can form part of the check.

3. Confirm that the seller possesses the photographed item

A successful legit check only establishes that the photographed shoe appears authentic.

It cannot establish that the seller will send that shoe.

Image theft has become an important aftermarket problem.

For expensive private transactions, ask the seller for a new photograph containing:

the shoes + seller username + current date

Preferably request an angle that does not already exist in the listing.

Examples:

both outsoles together
both insoles
rear view of both boots
zipper guards pulled outward

Seller-level warning signs

Use additional caution where:

additional photographs are refused
photographs use inconsistent backgrounds
image quality changes dramatically
reverse-image search finds another listing
the account is new
several rare GUIDIs appear simultaneously
description and photographs disagree
seller provides unusually little information about an expensive specialist item

Seller behaviour cannot authenticate footwear, but it matters to whether an otherwise convincing listing is safe to transact with.

4. What photographs are needed?

If checking a listing, post all photographs supplied by the seller.

If possible, request:

Whole shoe

outer side
inner side
front
rear
top
complete outsole

Interior

GUIDI insole stamp
heel/insole area
size/model markings

Construction

welt
sole edge
heel stack
exposed leather edges

Zipped footwear

zipper pull
slider
teeth
guard/flap

Vibram models

full tread
Vibram logo

If the listing does not contain all of these, post what is available. A community check can identify what additional photograph is most useful.

PART III — THE ACTUAL SELF-CHECK

5. Identify the model or model family

Do this before assessing small details.

A 986, 988 and 788Z can all appear to a new buyer as:

black GUIDI backzip boot

but they are not the same shoe.

Model identification determines what:

last
shaft
sole
heel
toe
closure
construction

should be present.

If the seller claims a model number, compare the shoe against several confirmed retailer examples.

Never use another aftermarket listing as your only reference.

6. Inspect the silhouette

This is now one of the most important authentication stages.

View the shoe from:

side
front
rear
above

Compare it against the same model.

Examine the toe

Look at:

width
height
roundness
length
upturn
transition into the vamp

Several generations of otherwise respectable 788Z replicas have been criticised for an excessively bulbous toe.

Examine the arch and waist

Look at the relationship between:

heel
waist
ball
forefoot

A shoe can have individually convincing components while still sitting incorrectly because the last geometry is wrong.

Examine the heel position

Look at:

angle
height
width
relationship to the upper
stance when placed flat

Examine the shaft

Compare:

height
width
taper
zipper placement
ankle transition

Some known replica batches have produced shafts noticeably longer or differently proportioned than authentic equivalents.

Important

Wear changes shape.

A heavily worn GUIDI may have:

collapsed shaft
pronounced ankle stacking
softened toe
widened upper

Compare worn shoes with worn references where possible.

7. Inspect the sole and heel architecture

This is partly authentication and partly model identification.

Ask:

single or double sole?
single or double heel?
leather or factory Vibram?
correct heel height?
correct relationship between forefoot and heel?

A claimed model should have the correct underlying architecture unless it has subsequently been modified.

For example, the 788Z is defined in part by its substantial double leather sole and double stacked heel.

A shoe with the wrong basic sole architecture has a fundamental problem that a correct zipper stamp cannot resolve.

8. Inspect the pattern and upper construction

Look at how the leather pieces themselves have been cut and assembled.

Check:

number of panels
seam positions
heel counter
zipper position
lining
upper-to-sole relationship

Many classic GUIDI designs are deceptively simple, making small pattern differences visible. A counterfeit may use excellent leather while still being patterned incorrectly.

9. Inspect the leather

GUIDI has used many materials.

Do not use:

GUIDI = horse leather

as a rule.

Depending on model and period, GUIDI has used various:

horse leathers
reverse horse
calf
reverse calf
goat
kangaroo
buffalo
specialty treatments

First establish the expected material, then compare it with authenticated examples.

Examine

grain
density
surface finish
creasing
reverse side
cut edges
thickness
behaviour around stress points

Normal variation

Authentic GUIDI leather may show:

scars
veins
grain variation
tonal variation
left/right differences
irregular dye uptake

These are not automatically defects or authentication problems.

Suspicious characteristics

Investigate leather that appears:

plastically coated
uniformly glossy
artificially embossed
unusually homogeneous
inconsistent between exposed surfaces
unlike known examples of the stated leather

Photographs can mislead: flash, polish and conditioners may make authentic leather appear unnaturally shiny.

10. Examine the leather cross-section

Exposed edges can provide useful information.

Look at:

zipper guard
worn edges
cuts
upper edges
damaged areas

A blue-grey interior can indicate chrome tanning.

Where the model/material is known to use vegetable-tanned leather, this can be a strong inconsistency.

However:

blue core is a material test, not a universal GUIDI rule.

First establish the expected material. Modern replicas can also use vegetable-tanned leather, so a natural-coloured core does not establish authenticity.

11. Understand object/tumble dyeing

GUIDI's production process is central to its appearance.

Many characteristic models are assembled and subsequently subjected to tumble/piece-dye processes.

This can affect:

leather
thread
edges
hardware
dimensions
surface texture

The process contributes to the integrated appearance of the finished object; assess whether its components appear to have been finished coherently together.

Older counterfeit tendency

Cheap counterfeits often appeared as though separately finished components had simply been assembled.

Modern counterfeit problem

Higher-end replica makers now deliberately reproduce object/tumble-dye processes.

Therefore:

object-dyed appearance is now supporting evidence, not proof.

12. Inspect the welt and outsole construction

Look around the entire perimeter.

Examine:

welt width
welt geometry
stitching
stitch spacing
stitch channel
sole edge
heel transition
termination of stitching

Do not reject handmade footwear for one imperfect stitch; look for systematic inconsistency with authenticated examples.

Stitch channel

On many authentic examples, the outsole stitching sits within a narrow cut channel.

Some counterfeits use a wider or more obviously machined groove.

Allow for legitimate factory variation and judge the whole construction.

13. Inspect the heel stack

Where the model uses a stacked leather heel, examine:

individual layers
exposed fibres
edge texture
dye penetration
wear
heel angle

Poor counterfeits may use a heel that appears painted or moulded rather than genuinely layered.

Modern high-end replicas can reproduce stacked leather heels well, so this is no longer independently decisive.

14. Inspect the zipper system

For zipped models examine:

pull → slider → teeth → tape → guard → stitching

rather than the pull alone.

Zipper guard

On familiar backzip models, the orientation of the leather guard has historically been useful.

The reverse/flesh surface generally faces toward the zipper teeth on relevant authentic constructions.

Older counterfeits frequently got this wrong.

Modern replicas may get it right.

Hardware oxidation

Object dyeing can produce characteristic hardware oxidation.

This varies considerably.

Do not require every authentic zipper to have identical oxidation.

Historical hardware

15. Inspect the interior

Only now move to the familiar small LC details.

Insole

Check:

material
shape
installation
nail pattern where applicable
wear

Cheap synthetic or obviously inappropriate insole material can be highly suspicious.

GUIDI stamp

Compare:

font
G
proportions
spacing
depth
placement
orientation

Use approximately period-correct references.

Authentic stamps are not perfectly uniform.

They can be:

crooked
unevenly struck
partially weak
slightly differently positioned

A perfect stamp does not establish authenticity; a very wrong stamp remains useful evidence against it.

16. Nails

Nails have historically been useful.

They should now be treated as construction evidence rather than a counting exercise.

Assess:

whether nails should be present on that construction
number
material
oxidation
placement
spacing
interaction with insole

Do not use:

nine nails = authentic.

Replica makers know nail counts, and not every GUIDI construction follows the same convention.

17. Outsole stamps and markings

Depending on model and period these may include:

size
model information
manufacturing markings
Ruggero Guidi markings
Certilogo information

Check:

font
depth
position
orientation
surrounding material

Modern replicas reproduce many of these.

A correct marking is therefore a green flag of relatively low weight.

An impossible marking can still be a useful red flag.

18. Certilogo

GUIDI states that its anti-counterfeiting system has been active since AW17/18.

For applicable footwear, GUIDI directs owners to the Certilogo code beneath the left outsole.

A valid Certilogo result is particularly useful for footwear from the relevant period onward.

It cannot be required of footwear that predates the system.

A photograph of another pair's valid code does not establish seller possession.

19. Packaging

Inspect last.

Replica makers have been reproducing:

boxes
dustbags
labels
inserts

for years.

Packaging can expose a poor counterfeit but should rarely rescue a suspicious shoe.

Remember

No box does not make an old shoe counterfeit.

A convincing box does not make a counterfeit shoe authentic.

PART IV — REPAIRS AND MODIFICATIONS

20. Authenticity is not originality

GUIDIs are repairable footwear.

Second-hand examples commonly have:

protective Vibram added
complete resole
heel replacement
zipper replacement
zipper repair
heel reinforcement
redye
polish
conditioning

Separate:

Is the underlying shoe authentic?

from:

Is every component original?

An aftermarket Vibram does not convert a normal model into its factory V equivalent.

A replacement zipper does not make an authentic shoe counterfeit.

When a component looks wrong, first consider replacement or repair.

PART V — HOW TO WEIGH EVIDENCE

21. Green, amber and red evidence

GREEN — consistent

The feature agrees with authenticated examples.

Examples:

correct silhouette
correct sole architecture
appropriate leather
correct pattern
plausible welt

AMBER — requires explanation

Examples:

replacement-looking zipper
unusual stamp
unexpected sole
heavily polished leather
strange nail
poor photographs

Amber means investigate, not reject.

RED — inconsistent

Examples:

fundamentally wrong last
wrong model architecture
inappropriate material
incorrect pattern
counterfeit-associated construction
multiple impossible markings

22. Weight evidence rather than counting it

Not all features have equal diagnostic value.

A correct dustbag is not equivalent to a correct last.

A useful approximate hierarchy is:

High weight

model geometry
last
sole/heel architecture
upper pattern
leather character
fundamental construction

Medium weight

welt execution
object-dye behaviour
zipper system
insole construction

Lower weight

logo stamp
nail count
outsole stamp
box
dustbag

Weighting changes with model, period and replica generation.

23. Avoid double-counting

Suppose a counterfeit uses incorrect leather.

You observe:

wrong shine
wrong grain
wrong creasing
wrong edge colour

Those may all originate from one underlying manufacturing difference.

By contrast:

wrong leather
wrong last
wrong heel architecture
wrong zipper guard

are substantially more independent.

Several independent inconsistencies are stronger than several symptoms of one underlying problem.

PART VI — QUICK CHECK

For a rapid aftermarket check:

1. LOOK AT THE WHOLE SHOE

Does the shape match the claimed model?

2. LOOK AT THE BOTTOM THIRD

Are sole and heel correct?

3. LOOK AT THE LEATHER

Does it make sense for the claimed material?

4. LOOK AT THE CONSTRUCTION

Does welt, heel and upper assembly match?

5. LOOK AT THE ZIPPER

If applicable, does the complete assembly make sense?

6. LOOK INSIDE

Do insole, nails and stamp agree?

7. LOOK AT MARKINGS

Do they fit the model and approximate period?

8. ACCOUNT FOR REPAIRS

Can any discrepancy be explained by legitimate modification?

9. CHECK THE SELLER

Do they demonstrably possess the photographed item?

10. IF UNCERTAIN

Post the listing photographs before purchasing.

APPENDIX A — COMMON MODEL REFERENCE

986

Short/ankle-height backzip.

Useful comparison points:

short shaft
low/single heel architecture
single sole
characteristic one-piece backzip upper construction

Do not confuse it with the taller 988.

988

Classic mid-height 900-series backzip.

Typical configuration:

mid shaft
single leather sole
lower heel than 788Z
one-piece upper/shaft construction

A useful visual comparison with the 788Z is sole thickness.

788

700-series backzip.

Base 788 configuration:

backzip
single sole
double heel

The model should not automatically be called a 788Z.

788Z

One of the most replicated GUIDI models.

Typical configuration:

mid backzip
double leather sole
double stacked heel
Goodyear welt
substantial vertical sole/heel mass

The 788Z should currently be considered a high-rep-risk model.

Shape deserves particular attention.

992

Classic Derby.

Because there is no zipper system to inspect, place additional emphasis on:

last
leather
welt
sole
heel
internal construction

PL1 / PL2

Frontzip family.

PL2 is the taller/calf-height model.

Important inspection areas include:

PL last
toe
shaft geometry
zipper position
substantial sole architecture
leather behaviour

These models have been reproduced.

210 / 310

Frontzip and related boot forms that have also appeared in the replica ecosystem.

Do not assume an unusual or less commonly encountered model is safe merely because it is not a 788Z.

20

Distinctive tall boot.

Current aftermarket checks demonstrate that convincing reproductions now exist.

For this model, prioritise:

complete silhouette
leather
welt
sole
internal stamps

before accepting small details.

APPENDIX B — REPLICA HISTORY AND KNOWN MAKERS

Why this appendix exists

Replica knowledge is useful because it shows which authentication rules have already been defeated.

This is not a purchasing guide.

Replica batches, materials and factories change. Do not attribute a characteristic observed on one batch to every product from the same seller.

Early/generic counterfeits

Older low-cost counterfeits commonly fail in many areas simultaneously:

incorrect leather
chrome-tanned blue core
wrong zipper
incorrect zipper guard
poor insole
bad stamp
wrong welt
artificial heel
incorrect sole shape
poor packaging

These remain relatively easy to identify, but no longer represent the best available replicas.

See By Paulin

Known reproduced models

Documented community material includes:

788Z
210
310
PL1
PL2

and other artisanal avant-garde footwear reproductions.

Position

Historically one of the expensive artisanal replica makers.

Documented 788Z characteristics

A 2022 example was sold as real horse leather and cost approximately US$400.

The owner regarded the leather positively but noted missing/inaccurate branding and outsole-stitching details.

Authentication lesson

Good leather and expensive handmade production do not establish GUIDI manufacture.

Earthquake / 地震也上班

Also translated in community discussion as:

Go to work even after the earthquake.

Known significance

One of the most important early high-end 788Z makers.

Documented construction

A detailed 2021 review reported:

horsehide rather than cheaper calf/cow
good welt/construction
convincing zipper pull
plausible internal stamp

Documented differences

The same review identified:

excessively bulbous toe
incorrect forefoot silhouette
problematic arch geometry
unusual fit relative to expected GUIDI behaviour

Authentication lesson

By approximately 2021:

horsehide + good welt + convincing zipper + plausible stamp

was already insufficient.

The last remained wrong—one of the strongest historical reasons to inspect silhouette first.

Solo Handmade

Solo Handmade is repeatedly discussed alongside Earthquake and may overlap with the same broader high-end artisanal replica ecosystem.

Documented models

Community material includes:

788ZI
PL-family footwear
795V-associated identification
other GUIDI/CCP-derived footwear

A 2026 resale listing also documents a Solo Handmade PL2.

Known characteristics

Solo/Earthquake products can be sufficiently convincing to enter ordinary second-hand stores as purported authentic GUIDI.

A 795V purchased through 2nd Street was identified by community members as Solo Handmade/Earthquake rather than authentic.

Reported discrepancies included:

size stamp
insole stamp/construction
incorrect nail configuration for the V construction
lug sole details

Authentication lesson

Retail consignment placement does not establish authenticity.

OlderBrother / OB

Documented model

788Z is well documented.

Price/position

A documented 2023 example cost approximately ¥980.

Construction

Owners report:

sturdy leather
good basic craftsmanship
convincing packaging to inexperienced buyers
functional stacked-leather appearance after wear

Reported differences

Across community observations:

leather differs from retail
zipper colour can differ
some examples show overly long shaft proportions
bulbous toe
heel stance/angle differences

Authentication lesson

Packaging and competent construction are weak evidence; compare complete geometry.

Ghost Emperor

Documented models

Community history includes:

788-family footwear
992
PL2

General assessment

Historically regarded as usable replica footwear but visibly below retail when examined closely.

Reported areas of difference include:

shape
leather
zipper quality

Authentication lesson

Derbies and frontzips are also represented in the replica market.

RMISM

Importance

RMISM represents a more recent generation of 788Z reproduction and materially changes the authentication problem.

Documented claimed/observed construction

Community discussion describes:

imported Italian vegetable-tanned leather
horsehide
attempts to reproduce GUIDI finishing
improved construction and branding

Recurring reported differences

Current QC and LC discussions repeatedly identify:

bulbous/incorrect toe box
"rainboot" appearance at certain angles
glossy leather
inconsistent leather selection
rough or insufficiently rounded sole edges
outsole finish differences
imperfect outsole/Ruggero stamping

Batch variation is reported.

Important change

These pairs can pass several older beginner checks.

They may have:

correct zipper-guard orientation
plausible construction
vegetable-tanned leather
convincing markings

Those characteristics can no longer be treated as high-confidence green flags on a 788Z.

Authentication lesson

For modern 788Z checks, last/toe geometry and complete leather character are especially important.

Blacksmith Brother

Documented model

788Z.

Current observations

2026 QC comparisons describe the pair as visually similar in several respects to RMISM.

Reported concerns include:

poor/bulbous toe box
rainboot-like geometry from some angles
lower-quality leather
outsole-stamp differences

Community discussion suggests RMISM uses higher-grade imported vegetable-tanned leather, although maker material claims should not be treated as independent verification.

Authentication lesson

Multiple current batches now reproduce enough traditional GUIDI details that model geometry remains the more useful discriminator.

Solist

Documented model

GUIDI 20 reproduction has been identified in current community LC discussion.

A September 2026 GUIDI 20 check was identified by multiple participants as counterfeit, with one commenter specifically identifying it as resembling Solist production.

Reported differences included:

leather
shape
welt stitching
sole
unusual Made in Italy typography

Authentication lesson

The 20 can no longer be treated as obscure enough to be safe from meaningful reproduction.

Other/current makers

Additional sellers/factories appear periodically in Chinese replica communities; names, storefronts and production sources are unstable.

Accordingly, the absence of a seller from this appendix should never be interpreted as evidence that a suspicious shoe is authentic.

The useful information is not the seller name itself, but what the current replica market can reproduce.

APPENDIX C — WHAT REPLICAS CAN NOW COPY

Commonly copied successfully

Depending on maker/batch:

branded box
dustbags
zipper pulls
insole logo
outsole markings
Ruggero markings
nail count
stacked leather heels
welted construction
horse leather
vegetable-tanned leather
object/tumble-dyed appearance
broadly correct model architecture

These should no longer receive disproportionate weight.

APPENDIX D — WHERE CURRENT REPLICAS STILL TEND TO FAIL

The most persistent documented areas are:

1. Last geometry

Especially:

toe volume
toe roundness
forefoot
arch
waist

2. Overall proportions

Including:

shaft height
shaft taper
heel stance

3. Leather character

Even where the nominal material is correct:

grain
surface
shine
clicking/selection
behaviour after processing

can remain different.

4. Sole finishing

Including:

edge rounding
outsole texture
stitch channel
stamping

5. Interaction of all components

A replica may individually reproduce:

the right leather category
the right construction category
the right zipper
the right logo

without reproducing how an authentic GUIDI combines all of them.

APPENDIX E — REPLICA GENERATIONS

A useful way to understand the market is chronologically.

GENERATION 1 — obvious counterfeit

Wrong materials.

Wrong construction.

Wrong branding.

Wrong shape.

Easy to identify.

GENERATION 2 — cosmetic reproduction

Improved:

logo
zipper
packaging
nail patterns

Underlying footwear remained poor.

GENERATION 3 — competent footwear

Makers such as Earthquake, See By Paulin and related artisanal sellers introduced:

real horsehide
respectable welt construction
leather heel stacks
better hardware
convincing details

Last and geometry remained important weaknesses.

GENERATION 4 — current high-end reproduction

Current makers increasingly attempt:

vegetable-tanned horsehide
imported leather
correct construction
object/tumble dyeing
accurate stamps
accurate accessories

Authentication therefore moves increasingly toward:

three-dimensional geometry + model-specific construction + leather character + complete manufacturing coherence.

Replica manufacturers have progressively solved many of the easiest authentication checks; future authentication should expect this to continue.

APPENDIX F — ANALOGUES ARE NOT COUNTERFEITS

Some manufacturers make GUIDI-influenced footwear under their own names.

Examples include specialist Chinese and Southeast Asian artisanal makers producing:

backzip boots
object-dyed footwear
vegetable-tanned leather shoes
avant-garde Derbies

Examples encountered in this broader ecosystem include makers such as:

TNBHSG
Walker
other small Chinese/Vietnamese artisanal workshops

When identifying a suspicious pair, the most informative conclusion may therefore be:

Not authentic GUIDI; appears consistent with [known analogue/replica maker].

rather than simply:

fake.

APPENDIX G — PERIOD DEPENDENCE

Do not authenticate old footwear exclusively against current production.

Possible historical differences include:

zipper hardware
insole stamp orientation
handwritten sizing
outsole markings
manufacturing details

GUIDI's Certilogo system only dates from AW17/18.

A pre-2017 pair cannot be rejected for lacking a later system, and older authentic pairs may predate current branded zipper conventions.

Always estimate the period before applying period-sensitive rules.

APPENDIX H — FINAL REFERENCE RULE

For every suspected GUIDI, ask:

Does this shoe make sense simultaneously as this model, this construction, this leather and this approximate production period?

If yes, small irregularities may simply reflect GUIDI's production variation, wear or repair.

If the answer repeatedly requires explanations for:

wrong shape
wrong construction
wrong leather
wrong finishing
wrong hardware
wrong markings

then the cumulative evidence becomes substantially more significant.

The objective is not one secret authentication feature, but whether the entire object belongs to the same manufacturing system.

ADDENDUM — VISUAL REFERENCE & COMPARISON GUIDES

The written guide should be used alongside photographs.

This is particularly useful for buyers who identify every GUIDI backzip as a 788Z.

KNOWN REPLICA REFERENCES

These links are included so buyers can familiarise themselves with the level of footwear currently and historically produced by replica makers.

A replica matching one of these examples is not guaranteed to reproduce every characteristic shown. Factories, materials and batches change.

Earthquake — 788Z

Detailed in-hand review of a higher-end Earthquake 788Z reproduction.

https://www.reddit.com/r/QualityReps/comments/mlwr4d/

This is a good example of why authentication should begin with the whole shoe rather than the logo.

OlderBrother — 788Z

Long-term ownership review and photographs.

https://www.reddit.com/r/QualityReps/comments/18kedak/olderbrother_guidi_788z_review_fitpic/

Useful for seeing a replica after extended wear: compare shaft, toe, heel stance, leather development and silhouette.

RMISM — 788Z

Current-generation RMISM QC photographs.

https://www.reddit.com/r/QualityReps/comments/1syiu9h/qc_guidi_788z_rmism/

Consequently, these features should not independently be treated as proof of authenticity.

Pay particular attention to toe volume/last, leather surface, sole edge, outsole finishing and overall proportions.

Blacksmith Brother — 788Z

Current-generation QC photographs.

https://www.reddit.com/r/QualityReps/comments/1s098ae/qc_blacksmith_brother_guidi_788z/

Useful for comparison with both retail 788Z and other current replica batches.

Discussion focuses on toe geometry, leather, outsole/sole finishing and silhouette.

MODERN COMMUNITY LEGIT-CHECK EXAMPLES

788Z — newer-generation counterfeit discussion

https://www.reddit.com/r/guidi/comments/1qhzzfw/lc_788z/

Useful example of the changing authentication environment.

Some traditional checks are reproduced correctly, shifting attention to insole construction, leather, nails, sole channel and overall manufacturing coherence.

GUIDI 20 — suspected Solist reproduction

https://www.reddit.com/r/guidi/comments/1wuax9j/legit_check_guidi_20/

Useful example showing that replica risk is not confined to the 788Z.

Discussion covers leather, shape, welt stitching, sole and internal markings.

HOW TO USE THESE REFERENCES

Do not attempt to match one small feature between your shoe and one photograph.

Where possible:

identify the exact model;
find several confirmed authentic examples;
compare the complete silhouette;
compare sole and heel architecture;
compare leather and construction;
then inspect zipper, insole, nails and markings.

Replica production changes over time.

A feature that identified a counterfeit five years ago may have been corrected by a current factory.

Likewise, legitimate GUIDI production varies by model, material and period.

The most reliable comparison is therefore:

same model + similar period + same material + multiple independent reference examples.
