The fundamentals of a sock are pretty straight-forward. A good running sock, however, will have all the qualities present in Under Armour’s Full Cushion Run Socks. A Lite Cushion provides extra comfort and shock absorption at key impact zones. Under Armour’s signature Moisture Transport System helps wick sweat away from your feet. The socks have built-in ArmourBlock® Anti-Odor technology to help prevent the growth of odor-causing microbes. Foot fatigue is reduced with the embedded arch support. Strategic ventilation dumps excess heat where you need it the most. Made from Polyester/Spandex®.
