I really love these socks, which I wear as dress socks with suits and skirts.  The white bands are so high up on the calf that they aren't noticeable under long winter skirts and dresses, and the socks are much sturdier and warmer than regular dress socks. They are even reversible!  They are black when reversed.  They have a little invisible compression band at the ankle that actually eliminates edema.  WHAT?!?  I would order more, but I basically have 20 pairs now, since I can wear them as blue or black.  I only wish they had an option without the white stripes...
I'm 6'0" and they come right up to my knee, and appropriately snug on a large calf. They would fit someone up to 6'3" and probably 275lbs, at least to men's size 11 shoe.
