The Under Armour UA Performance Tech 3pk Crew Unisex Socks are made of durable material that wicks sweat and dries quickly. The new Locked-In Fit construction ensures that the sock holds firmly on the heel. The midfoot is padded for comfort and protection, while mesh panels on the instep increase breathability. Built-in arch support helps reduce foot fatigue. The pack contains 3 pairs of socks.
