The brothers behind Fitsok are avid runners and were tired of getting the average cotton socks that would wear out within days. After countless holes, loose threads, and socks that just plain fell apart, they endeavored to create a sock that would last not only through the toughest runs but yours as well. These socks are made in the USA, and any number of pairs would make great additions to the arsenal of any level of runner.
