The Men's Trail Repreve Single Layer Sock is perfect for trail and fell running and mountain biking. The 1000 Mile Trail Sock is anatomically designed to give comfort and support during your off-road running and racing. The padded heel extends to protect the achilles tendon, toes and ball of the foot. The combination of fibres, including the latest REPREVE ® recycled yarns, helps reduce friction, wick moisture and dry quickly. Arch bracing provides a customised fit with no slippage. Ventilation zones allow the foot to breathe and maintain an even temperature.
