I love these socks. I have bought 4 pair and will buy more when these wear out - which from the way they hold up will be a long time away. I wear them to exercise in and also I wear them to bed at night. My feet get cold and these socks are so comfortable - my feet don't get hot, just warm enough to sleep comfortably. I can't say enough good things about these soft thoroughly wearable socks. They are a really good buy!
