Our Socks are areesigned with ventiltion channels knit into the sides of the sock to provide ventilation and to dissipate moisture, all part of the Moisture Management System. The socks are designed with a low profile toe seam that is placed on the top of the oess, rather than below, and hand linked to provide a comfortable fit. The instep is articulated to improve comfort by keeping the sock in place during activity and we eliminated a heel seam, to reduce chaffing and blistering.
