Terrific socks! Was getting slight blisters and toe irritation on long runs 8+ miles - tried vaseline, etc - friend suggested these and they are AMAZING! Ran 7.5 yesterday - NO skin/toe issues at all - like I ran 1/2 mile! :) I am 11.5/12 shoe - Large sock fits perfectly.

Love the fact that there are no seams to rub. They are pricey but good.

Coolmesh II Socks Closeouts

These are the older design. They fit "thick boned" people like myself well. I wear Men 8 regular width shoes. Before I trained wearing minimalist shoes, I had to wear 8 1/2 EE or 4E. Anyways, these socks fit well, no blisters, and comfortable.

Always loved these socks. But in the past I got mediums because that's more or less what my size fit. They were very good socks but still had a slight blister problem. However, I am extremely prone to blisters on my left foot (just below big toe (bunion area). This time I ordered small, knowing that they may be real snug. No, they are snug but not a determent. They are snug enough so the material doesn't slide or bunch at all. Ha, fit like a good glove or in this case a good sock should. Oh, I got Stride qtr sock, Ultra thin, Coolmesh II
