Our active fit socks are made from combed cotton with mesh vents and a reinforced heel and toe. And to cradle the contours of your feet, the socks sport a Y Gore Seam, deep heel pocket, and an elastic arch band. Are you wondering how we printed those wicked designs on our Active Fit socks? It involves a heat press, heat transfer paper, and special sublimation inks. Because we sublimate the inks right into the sock fibers, they will never lose their color, even after multiple washes. We guarantee it!
