I think unless you have really wide feet, you probably can because it's quite long. I actually put an insole cause there was slight heel slip, because the collar doesn't really hug your ankle. I'll try to take a pic of how much toe room I have in my 11 1.0s compared to the size 10 y3s
I got them from Gravitypope, someone in this thread posted them when they were on sale and I think it's probably gone by now. They fit 1/2 size large on me, my true size is 10.5 and I got a 10 in these, I wear an 11 in UB 1.0s and 10.5 in 3.0s for reference.
I've had good experiences selling on both StockX and Goat and they're pretty much the same to me. Both will tell you how much you'll make when you list the price, but I think StockX doesn't show the 2.9% PayPal fee so just go with whatever will pay you more. I don't sell on eBay anymore with all...
Sorry, I'm not trying to come off as an *** but that's why I mentioned to go by EU sizing. It'll take into account whatever size difference that brands use(1 for Adidas, 1.5 for Nike), so it's easier to just go by that.
