I've been very happy with these socks. They're a nice balance of being more supportive than regular socks without being too restrictive. I ordered a small and wear a women's 6.5/7 shoe and they fit well.

My regular shoe size is somewhere between a women's 8 and 9 and maybe a 10 for a boot. They were too small for me. I must return them! Otherwise, they seemed good quality.
