Our Referee Socks are designed with comfort and performance in mind. They feature a double welt top, built-in arch and ankle compression zones, and a smooth toe seam for maximum breathability and comfort. The heel/toe design includes a cushioned sole for extra support and shock absorption, while the blend of 75% Polypro, 12% Nylon, 10% Elastic, and 3% Spandex keeps your feet cool and dry.
