The crew length 1000 Mile Approach Sock is designed for maximum comfort with today’s technical approach footwear. The 100% Tactel® inner layer stays with the foot, wicking away moisture, whilst the soft wool-mix outer moves with the shoe, reducing friction and helping to prevent blisters and reduce wear. The unique combination of fibres maintains a comfortable temperature for the foot, making this the perfect warmer weather outdoor activity sock to wear with lightweight boots as well as approach/trail shoes and sandals.
