It all started back in 1921, with just 25 employees. Today Renfro Socks employs 5,000 people around the world. The website sells its own designs alongside those from big brands. For example, customers can find athletic socks from Spalding and Fruit of the Loom, playful designs that include The Birth of Venus in foot-covering form from Hot Sox, those that stand up to heavy usage from Carhartt, and compression and other medical socks from Dr. Scholl's. Socks that aren't up to your feet's standards can be returned through Renfro's hassle-free 90-day return policy.
