The 1000 Mile Fusion Walking Socks offer a unique blend of padding and double-layer technology to prevent blisters. These socks provide comfort and protection with padded zones on the heel, toe, and Achilles tendon. The high-volume Merino wool offers warmth, making them ideal for cooler weather. Features include Achilles tendon protection, arch bracing for support, and padded comfort zones on the toe, heel, and ball of the foot. The double-layer construction eliminates friction between the foot and shoe, while the Tactel inner layer wicks away moisture to keep feet dry and cool. The outer layer is composed of 40% Merino Wool, 29% Nylon, 23% Polyester, 6% Cotton, and 2% Lycra. The inner layer is 100% Tactel®. For best fit, carefully pull on the sock to ensure the fitted heel and toe box sit correctly.
