Bridgedale's best selling hiking model, the Men's Endurance Trekker Sock is categorized by Backpacker Magazine as the best for three season backpacking adventures. To ensure comfort and protection the Men's Endurance Trekker Sock has anatomically targeted dense midweight cushioning in the Achilles-heel, 360-degrees around the forefoot, and toe box. The unique knitting construction, throughout the ankle area, features a deep heel pocket with easy ankle flex design and moisture moving mesh. Crafted to be used with full height medium volume footwear, additional knitting is strategically placed over the instep, up the back of the calf and around the cuff for all around cushioned comfort. Bridgedale's Woolfusion hybrid sock yarn fuses natural Merino Wool with performance Endurofil micro fiber to keep the foot dry and comfortable by absorbing and wicking moisture.
