They stay up and don't strangle my legs. So soft and cushioned yet my feet stay dry and just the right temp. I'm seriously looking at placing these socks at the TOP of this year's Christmas wishlist to upgrade my entire sock wardrobe. So comfy, like the shirts....I don't want to take them off at the end of the day!! Need sleepwear, just wear your clothes to bed, their clothing and socks are seriously more comfortable than many of pajamas too!!
