I really like these socks, they keep me nice and toasty and fit well inside my winter boots. I wear a Women's 8.5, and the footbed size seemed appropriate. That being said, I have muscly/athletic calves and this was great up to the band at the top... I wore them to bed on a cold night, and could feel them pinching too tightly so I took off 1 star because they aren't spectacularly stretchy at the top and my legs aren't gigantic.
