Experience superior comfort and protection with these expertly crafted 1000 Mile Double Layer Trainer Liner Socks. Designed for ultimate performance, they feature a unique Tactel® inner layer that stays with the foot, wicking away moisture to keep you cool and dry. The outer layer moves with the shoe, and the lack of friction between the layers helps prevent blisters and reduces wear, backed by our BLISTER-FREE GUARANTEE. The socks offer top venting for superior breathability and arch bracing for extra support. With integrated Heel Power technology, they prevent slipping, and the shaped design with a higher tab protects the ankle. Tactel® fiber ensures the socks are soft, lightweight, and fast-drying. The outer layer is made from 65% cotton, 34% nylon, and 1% Elastane Lycra®, while the inner layer is 100% Tactel®. Available in sizes M (6-8.5 UK/EUR 39-42.5), L (9-11.1 UK/EUR 43-46.5), and XL (12-14 UK/EUR 47-49).
