MAXIMUM SWEAT AND MOISTURE MANAGEMENT - Our signature Olefin fiber is a light-weight, high performance fiber that wicks moisture and dries quickly, so your feet stay dry and blister-free wherever your adventures take you. BREATHABLE DESIGN - Featuring upper channels that provide ventilation for increased breathability, preventing hotspots and keeping your feet cool. CONTROLLED SUPPORT - Moderate compression throughout the arch band gently hugs your feet to support your muscles and keep your socks in place. REINFORCED HEEL AND TOE - For maximum durability in abrasion prone areas, we’ve reinforced the heel and toe. Go ahead, test its limits.
