These socks are very comfortable and fit nicely.  They come up about mid calf on me which is higher than the picture seems to show in the product description.  They are thicker than a dress sock, but thinner than a normal crew sock.  I would have been very happy with them if the hem at the top of one of them didn't come unraveled the first time I wore them.  Amazon is exchanging them with another pair at no cost.  Hopefully the new pair will not have the same issue.
