Thanks fellas, I'll try them on in store, if they're too snug, I'll throw my brother the oop. He's a size 9 and I've been putting him onto any and all boost shoes lately.
Just ordered the white ub's a half size down from my normal size. (Thanks to that champs link) I have other ultras that fit great in my true size, but I have a narrower foot. You guys think I should be ok? I'll try to get down to an Adidas store to confirm.
