The Thorlos anatomically designed, patented terry padding protects your feet from pressure, impact and shearing force. The padding reduces static pressure and impact, and diminishes shearing forces through what we call the 'Control·Slide®' phenomenon . This means that instead of the tissues on your feet moving in opposite directions, the terry padding moves under your feet, transferring the movement from the tissues of the foot to the terry padding itself. And to ensure that your feet are protected from the adverse effects of accumulated perspiration inside the shoe, s urface moisture and water vapor are effectively channeled to the outside of the foot where they can be evacuated through the shoes. This is accomplished with the Thorlos proprietary yarn combinations that include THOR·LON® Acrylic, CoolMax® and other high tech fibers that 'wick' moisture away from the foot."We make socks, but we sell foot health."
