Thorlos started in the early 1980s crafting socks, not as accessories or fashion statements, but as devices that could improve foot health. Today, the socks are made completely in the U.S. out of a factory in Statesville, NC, still dedicated to this mission. The secret of Thorlos lies in the fiber and padding. The synthetic acrylic fiber provides phenomenal moisture management and protection from the shoe, while dense, strategically placed pads protect the foot by absorbing shock from the impact of each step. Thorlos also designs socks for specific shoe types and activities, including military training and combat. When your feet are happy, you can focus all your attention on performing at your best.
