I bought a few pair for stocking stuffers, and a pair of over the calf socks for me. Of course my wife and daughter are already wearing them and love them. My wife is a Bombas freak, and said these are just as good, if not better than the Bombas. They both get very cold feet, and commented how warm they are. I'm loving mine so far. Wore them to work tonight. So far, they feel great in my steel toed boots. I don't expect to change my mind through the night. These are great.
