I would go at least 1/2 size down from UB size. I am:
TTS 8 or 8.5.
UB 8.5 (I can put an 8 on but my toes are not comfortable. I could probably get away with a 9 also.)
Y3 PB - I had an 8.5 and believe I could fit an 8 with an insole and still have some wiggle room, or 7.5 without an insole, but...
Aspecto shipped my order in a bag a couple weeks ago. I'm surprised how good of condition a shoebox arrived in a bag but my box did have some creases in it.
UK is a half size down.
US 8.5 = UK 8, but I wear US 8 typically and 8.5 in UBs but this Y-3 feels like I'm going to clown school...
LOL, I'll save the vets from answering.
Winnsports is legit
Revup is legit
Generally, if the seller ratings are insanely high, you can assume people aren't giving 5 stars for fakes.
Champs Sports website has OG Black/Purple Women's 9 (Men's 8) available for shipping if anyone is interested.
