I ordered these to wear in the winter. I wore them out the other day and they were very nice. The socks were warm and they did not fall down. I will say, if you have a chubbier calf you may find the top of the sock tight on your calf. I don't, but I did notice that the top is snug but that is why they stayed up good for me. I did not have any trouble with the little nubbies on the bottom of the socks sliding or slipping off the bottom of my foot, they stayed in place. All in all very nice to wear.
