I bought two pairs of these to wear specifically with my snowboarding boots. They fit great and are super comfortable! My feet were warm and dry all day. They fit right up to about 3 inches from my knee. I had a pair of wigwam socks when I deployed to Iraq, and loved them then, so I decided to give them a second shot. I was not disappointed. The quality and build of these socks are great. I will definitely buy more wigwam products in the future!
