I love these socks. I wouldn't call them knee high though, they are like maybe halfway up your calf. I know some of the reviews complained they are too big, but my feet are size 7.5 WIDE and they fit pretty well. I mean they are big and fuzzy, but it's really not that big of a deal. I basically wear them around the house instead of slippers. They are nice and warm, not too thick for me. They do however get a bit fizzy at the bottom when walking around so much because of the yarn used.
