A sock within a sock. The 100% Tactel® inner layer of the 1000 Mile All Terrain Women's Sock stays with the foot, wicking away moisture, whilst the soft wool-cotton mix outer moves with the shoe. The unique combination of fibres, which includes merino wool, and top venting maintain a comfortable temperature for the foot. Arch braces on both layers help prevent unwanted movement, even on severe slopes. Recommended for all types of off-road activities, these crew length socks will help you keep going when the going gets really tough.
