These socks are thick and warm.  They keep my feet nice and toasty and are so thick they add a little padding to your walk.  After washing several times they have started to shrink a bit, which can be a problem for me because I have size 10 womens feet and need them to be long, but with some tugging after drying they still fit ok.  A little pricey so I'm not sure if I'll buy them again.  If I needed super warm socks more often they would be a good investment.
