Rating : - Great, Long-Lasting Socks
I've been wearing these socks for many years under my cowboy/motorcycle boots because I don't like the feel of the boots against bare skin. I first purchased them at Macy's and discovered that they wear like iron and stay up through hundreds of washings.

Highly recommended!
