Many runners prefer thin socks. Thin socks provide little protection from moisture, friction and blisters. The Drymax Hyper Thin Running socks are able to protect feet much better than other thin running socks because they have our race proven Dual-Layer Sweat Removal System. This system moves moisture off the skin through the inner Drymax layer to the outer absorbent layer. The Hyper Thin Running socks are for use in mild to hot conditions, keeping feet cool, dry, comfortable and odor free - all day long. Material: Drymax / polyester / nylon.
