Socks are made in Pakistan and are sized way too small.  I bought size 10-13 and I wear an 11 shoe.  It is a struggle to get these on past my heel/instep and then they are too binding on my lower leg.  Non-Binding is not a correct description.  There is a reinforcement band around the top of the socks that leaves a deep impression in you leg.  Otherwise, the quality seems good.  They are fairly expensive, but I can't testify to how they hold up, since mine are going to Good Will.
