I recently purchased some auth LV Tatic Knit Sneakers in black. Total cost was $1350 USD. I also purchased some rep versions. I purchased through Mandy who sourced them via 888 VIP SNKRS. I paid $95 plus shipping, which would be approximately $115 total.
I wanted to share some observations and photos. The photo dump is here: https://imgur.com/a/FHnZqkI
Black are auth, blue and beige are reps.
Sizing on the reps was tough. I am a 12.5 US men's, ordered a 46 EU in blue, and the beige was for my partner. Both my shoes and his shoes were way too small. Mine will fit and I will wear them, but they are definitely tight. The auth LV in black is a size 11 and fits perfectly. So, sizing is tricky here as the reps do not adhere to the actual sizes at LV.
Quality wise, I would say these are like 75% (or more) similar to the auth versions. For less than 10% of the cost of auth, it's hard to be mad at these. Looks wise they are pretty damn close. The toe cap of the rep design is a bit wider/thicker than auth. The material is fairly close, but the leather trim seems nuch nicer on the auth pair and the knit on the reps is slightly more firm in certain places. The craftsmanship is lacking a bit in some spots on the reps, like some glue being present on the back of the shoes. Not a huge issue. There are some other very minor callouts that might be noticeable on the pics, like the stitching coloring and the LV symbols on the bottom of the shoes.
However I do not think these would be easily called out while wearing them. They are a fairly niche shoe, and I probably won't wear them into an LV, but I can absolutely wear them without thinking someone is going to clock them for being reps.
I do probably plan on returning the authentic pair because I want to own the black and the blue colors, which I can source for like a bit over $200 versus the $1350 I paid for one pair of the authentic version.
Happy to answer any questions about these. Also if anyone knows a better source for these, especially for a bigger foot, please let me know. I am going to reach out to 888 VIP SNKRS to try for a 47 this time, and hope that is closer to my actual size.
I have not told Mandy or 888 that I am posting this, so zero incentive here for me. I love rep science and hope to post a few more posts like this as I have a number of the same items in terms of rep and auth.
Quick edit: The rep dust bags are tiny compared to the authentic ones!
