The crew length 1000 Mile Approach Sock is designed for maximum comfort with today’s technical approach footwear. The inner layer stays with the foot, wicking away moisture, whilst the 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.
