These are ABSOLUTELY the BEST socks I have ever purchased. I am an avid walker and I always end up with hot spots or blisters - not with these socks! They are padded in just the right places and the wool soaks up any sweat. I was worried about the wool being itchy, but not at all! They are soft, but durable and I bought three more pairs! I love these socks! I wear a size 7 shoes and bought a medium and they fit perfectly.
