I had my doubt when buying this Asics because I read the size came a little bit small, luckly for me most 8 1/2 snikers (my size) fit a little bit loose to me but not enough to be an 8, these fit to me like taylor made. So if most of your snikers fit tight to you, you should probalbly ask for one size up. Aside from that matter, they look awesome and are very comfy. I have worn them to play tennis only 3 times so i have no comments about durability.
