Update: Definitely don't get these but go for the puma "forever faster cool cell" socks if you want socks to run or work out in, like me. Just got them in today and they have the sport cushion, arch support, and mesh for breathability.

Original review: These seem pretty overrated. Besides brand, they're not much different from my Avia socks from walmart. These are thin and have no cushion at all, just that arch support, same as My avian socks. My feet didn't get that happy feeling they usually get from new socks as these feel the same as the old ones. Also, they look like they'll get holes soon. We'll see how/if they last. I normally wear a 7.5 shoe. The package states it's for shoe size 5-9.5.
