Ok, I have never spent so much money on one pair of socks! But, they are worth it. My toes are toasty. I have cold feet and cold hands syndrome which is Reynaud's syndrome and once I get cold, it's very hard to warm up. First and most important, they are made in the USA. Oh, did I mention I wear size 11 shoes? So they are large enough for my big feet. The socks are also marked for your right and left foot. Also I would not call my calves small, like my mom's, and they knee highs are great, they stayed up all day and didn't cut off any circulation! I purchased both the smartwool's and I prefer these over those.
