Quite possibly the most comfortable sock you'll ever wear. Constructed with multiple zones of compression and fabric blends for increased blood circulation, heat reduction and moister wicking. Made of 80% Coolmax, 8% nylon, 8% spandex, and 4% rubber, these socks keep their shape and fit all sizes comfortably, even under the most rigorous of activity. In combination with the short 5.11 boots, the 3 Pack Ankle Sock rounds out the Shock Mitigation System to protect your feet, and keep them dry and comfortable. These socks are specifically made for a women's foot and also make great athletic footwear for sports and work-outs. Imported.
