3/21/15 Update: After about 4 years of having these socks, I have to say I'm impressed by how well they've held up.  Some of them are getting pretty thin on the bottom, but that's to be expected considering how long I've had them.  I'm upgrading my review from a 4 to a 5, because I think for the price, these are excellent wool blend socks.  I still have to fold the top down a little so it doesn't cut into my leg, but that's really no big deal.  (FYI -  If I measure from the floor to the top of the sock when it's pulled up all the way, it measures 10", and at that point my calf is 12.5" around.)

These are really great socks - soft, warm, and quite cozy on a cold winter day.  For the price they may be the best thing available!  My only complaint is that the elastic at the very top of the cuff cuts into my ankle/leg after wearing them for a while.  I find if I fold the top over just a little bit I don't have the problem - but this is why I'm giving the socks 4 stars instead of 5.  I have other great wool socks that I don't have this problem with - but they also cost a lot more!  I would definitely buy these again.
