Combining high-tech HeatGear fabric construction and Under Armour's signature moisture transport system, the HeatGear Over-The-Calf Athletic Sock works to wick away moisture and accelerate evaporation so your feet stay cool, dry, and light. ArmourBlock technology helps prevent growth of odor-causing bacteria, keeping feet fresher longer. Strategic cushioning is built into the sock for maximum shock absorption and protection. Embedded arch support reduces foot fatigue for long-lasting wear, while the seamless toe provides added foot comfort. The fully reciprocated toe and heel construction conforms to the shape of the foot and provides superior comfort. The HeatGear Over-The-Calf Athletic Sock is made from a durable blend of 95% polyester, 3% nylon, and 2% spandex fabric. One pair per pack. Imported.
