These Under Armour Performance Tech socks are designed for athletes, keeping your feet cool and providing arch support. The durable material wicks sweat and dries quickly, while the new Locked-In Fit design ensures the sock stays securely on your heel for an adjustment-free fit. Medium cushioning throughout the foot offers comfort and protection, and mesh panels on the top of the foot enhance breathability. Built-in arch support helps reduce foot fatigue. Each pack contains 3 pairs of socks. Made from 98% Polyester and 2% Elastane. Imported.
