Lightweight Athletic Half Calf Socks We want to put as little as possible between you and your running shoes. That's why we invented this incredibly lightweight running sock. It's cushion-free, but still soft and comfortable, with special performance yarns that wick away sweat while you run. Basically, it's a more minimal running sock.
