Combining high-tech HeatGear fabric construction and Under Armour's signature moisture transport system, the Rush 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 reduces foot fatigue for long-lasting wear, while the True Seamless Toe provides added foot comfort. ArmourFit elevated support in key arch and ankle areas yields a tighter, more secure fit. The HeatGear Rush No-Show Cushion Sock is made from a durable blend of 81% polyester, 16% nylon, and 3% spandex fabric. Two pairs per pack. Imported.
