I wear 9 in just about everything buy syndicate Era's, which I wear 9.5 in, nd when I owned the red colorway of these is a size 9, they were SO tight. They barely fit. I think you'd be solid with a 9.5 Memo. Since then I've gone back and conidered buying a new pair and I always look for 9.5's.
Hope I could help!
Looking to buy:
.Blends Sk8 Hi in black, 8-9.5 would be accepted. If anyone here has a pair I will trade serious heat for them.
.007 Grime Slip On's (Claw, not the Skull version) Will pay healthy prices for these. Shoot me a PM.
