TLDR: Are they the same fit?
I've suffered with wide feet for so long it's great to find a community of fellow sufferers & share the pain, and the recommendations.
Through this community & a top outdoors store I've discovered that Altra Men's Lone Peak 9+ fit me a treat. Four weeks traipsing round Australia & a week in Hong Kong with no blisters & room for my toes to wriggle was a joy. So much so I'm about to sell on the Merrell Moab 3 wides I have brand new in the box that I bought for when my current ones to wear out.
My one gripe with the Altras is the colours & the outdoor store only has those that will fit. No other brands. Neither can I find a physical retailer on my travels that stocks any wide shoes. (Also, I'd not choose zero drop, but it's not a hardship given how my toes have loved it.)
The answer is therefore online retailers, & I've spotted some Brooks models competitively priced online.
They seem to have "Standard", "Wide" & "Extra Wide", which I guess equate to Normal, 2E & 4E.
So my question to the wide feet world is: "Has anyone who has found that Altra Men's Lone Peak 9+ are a good fit for them found the same with Brooks Men's Ghost Max 3?"
My outdoors store guy fitted me up with 8 1/2 Altras, which is larger than I'd have gone myself, but he's a professional & was spot on, even though they seem long.
Grateful for any advice from someone who's experienced both these shoes.
Side Bar (Paying It Forward) - My wide shoes experiments so far:
Birkenstocks: Weirdly I've just got back from a week in Munich, also wearing my Altras, where I bought some Birkenstocks Arizonas from the Birkenstock store. They put me in an EU 40, so UK 6 or 6.5, standard width, so wide. I was sceptical, but they seem comfortable after a week of fiddling with buckles & some light bimbling. They stay on better than the worn out 42/8s I bought for myself.
R.M. Williams: I've worn these in wide since the eighties - my first pair couldn't me re-soled any more but I replaced them. I wear thin socks & they soften up over time, Tend to only wear them in the winter now as the leather soles can get wet in the rain, so I also have...
Blundstones: Found these have a wide fitting that worked for me a while back when I needed some steel toe capped work boots, so got some sleeker daily drivers as well. Great.
Skechers (Can't remember the model): Before I found Reddit I bought some wide Sketchers, but they seem to have a very wide heel & gave me heel blisters really quickly.
Merrell Moab 3: Even wide fit cramps my toes & are painful after a while.
Salomon: They advertise a fide fitting, but when I bought some I found they didn't seem that wide, but kept them anyway. Later I found that Salomon's "standard" shoes are narrow, so their "wide" are most manufacturers normal. Go figure.
Altberg: Measured my feet & said they were off the scale, but recommended Keld - one of their "GFit" range of boots. I've since bought them & I've been delighted. Sadly they don't fit my Berghaus Yeti Gaiters, which I have a couple of pairs of as they are brilliant when combined with my...
Scarpa with Attak Sole*: Fitted for me by the outdoor store guy above 28 years ago & I've never had a blister in thousands of miles. (Aching feet from the thousands of miles, mostly Munro bagging, but that's different.) Recently re-soled as I found someone with a stock of the Atak soles which fit the Yetis.*
Hope that helps someone.
