SmartWool PhD Run Light Micro Men's Socks Customer feedback

Comments: I love these socks! I don't get blisters in them! I run anything and everything in these. I have completed multiple half marathons, half iron distance triathlons, a marathon and trail runs in these. The only down side, besides the cost which they are wroth, is your feet get a little hot in them. I still wear them in the 100 degree heat in Oklahoma.
