These socks are pretty awesome. I wore them on my last 13.1 race, and my legs are pretty sore expect for my calves, which I attribute to the socks. I also enjoy having the ankle support from the whole sock, versus just the calf sleeves. My calves actually feel fine, as if I hadn't even run 13.1 miles. My quads on the other hand are pretty sore.
