Guaranteeing that their double-layer design will keep you blister free during wear, 1000 Mile put a lot of store in the effectiveness of the ‘sock-within-a-sock’ construction they use for the ladies’ 1000 Mile Ultimate Heavyweight Walking Sock. The design promises to put a stop to the transfer of friction from shoe to skin, ensuring blister-less walking comfort. The soft, smooth Tactel inner moves closely with the skin, efficiently wicking away moisture to keep you comfortable, while the outer is a thick, warm, wool rich knit that moves with the shoe. A ribbed leg and built-in arch bracing gives these socks a great fit, with natural high durability and insulation from the wool blend, ideal for whatever the season and whatever the weather you’re walking in.
