I've bought these a few times now as I use them frequently for my winter outdoor adventures. Recommend sizing up if you're on the fence between sizes. I'm a size 8.5/9 and found the large to be the dialed fit.

My wife uses these when she works because she has to stand all day long. They seem to help with her circulation while squeezing her legs off!
