I am in love with these socks! I wear a size 9 to 9 1/2 shoe, depending on the type of shoe. I have problems with socks being too tight at the top and strangling my poor legs. These are perfect! No tightness, no strangling, just soft, stretchy comfort. I wear them with steel toed boots at work, and they stay up the whole shift. Sometimes my feet get a little sweaty, but it's definitely not bad enough to complain about. They are so soft and warm. The bottom also has a bit of thicker material, which is awesome. I love these socks!
