Good sock; careful when cleaning
This sock is extremely soft and wearable. I bought the medium for a size 8 foot (I'm a small guy) and after one wash it did shrink a little in the drier. At first I had a horrible feeling of "this is never going to fit again" but after putting it on it stretched out nicely. Very snug, very warm. I would choose these over a SmartWool hiking sock, as those tend to build up moisture a little more than these. Less stray strings as well after washing. Would suggest very low heat when drying or line dry (directions say low heat; I'm a guy, I don't read directions half the time).
