We all have such masterpieces on our feet by now,... The high shaft keeps the calves nice and warm and therefore the feet too. We call them Haija socks because they are for sleeping in... good foot climate, no sweating or anything, and you can easily take them off when you`re half asleep.... When I`m wearing these socks, I know I`m at home and I can do whatever I want, nobody cares how stupid it might look. I love these socks. It`s kind of highly private e.g. when you`re very busi(ness)... :))
