Combining high-tech HeatGear fabric construction and Under Armour's signature moisture transport system, the Rival No-Show Cushion Sock works to wick away moisture and accelerate evaporation so your feet stay cool, dry, and light. ArmourBlock technology helps prevent the growth of odor-causing bacteria, keeping feet fresher longer. The Lite Cushion footbed provides shock protection and space compensation. Embedded arch support helps reduce foot fatigue, while the True Seamless Toe provides additional comfort. ArmourFit elevated support in key arch and ankle areas yields a tighter, more secure fit. The HeatGear Rival No-Show Cushion Sock is built from an ultra-durable blend of 80% polyester, 17% nylon, and 3% spandex fabric. Two pairs per pack. Imported.
