Combining high-tech HeatGear fabric construction and Under Armour's signature moisture transport system, the HeatGear Athletic Crew 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. Embedded arch support reduces foot fatigue, and the Perfect Fit toe helps eliminate bunching and chafing for all-day comfort. The Comfort Top delivers a secure fit without being too tight, while the cushioned footbed provides maximum shock absorption and protection. The HeatGear Athletic Crew Sock is built from a durable blend of 88% polyester, 11% nylon, and 1% spandex fabric. Four pairs per pack. Imported.
