During the early years of the company they manufactured socks specially for runners. They later started manufacturing socks with cushy heel padding and low-friction fibers for other activities. Since then, the company expanded its production to 32 different types of socks, specifically designed for sports like basketball, tennis and golf; and other activities like the military training and Western boots. The company also has a production line of casual socks, and lighter-weight socks for performance athletes.
