CoolMax CoreSpun fibers wick moisture away from the foot to allow fast evaporation, while providing an excellent defense against blisters. CoolMax is on the inside of the sock where it belongs and the nylon on the outside to provide lasting durability. The cuff uses Lycra to offer a truly gentle, supportive ankle band. Made in USA.
