These socks are sooo warm they're almost too warm! However, I have had a few problems with them! I wear size 10 shoes so at first ordered the L/XL size and they were WAY TOO BIG! I was shocked! I exchanged right away for the S/M and they fit perfect. After a few wears and washes the seem are comming apart! I'm going to return them again and hope the quality is better, if not I will keep returning for new ones because they are soo warm and comfortable!
