I bought some of the Point6 lifestyle medium crews socks for my husband last Christmas. He loved them so much, he ordered several more of the same one. He is an airline pilot and his feet get quite cold in the cockpit year round. The lifestyle medium crew keep his feet nice and warm. Another wonderful benefit he just loves about them is that they never fall down. He does a lot of walking in airports and these socks never fall down. He is quite impressed with their quality as well. I just ordered six more pairs for him for Christmas. I have washed them numerous times and they still look great. They truly hold up so well.
