The 1000 Mile Ultimate Walk Sock is perfect for walking, trekking and hiking as well as general training, Nijmegan and D of E expeditions. A sock within a sock, the 100% Tactel® inner stays with the foot, wicking away moisture, whilst the soft wool-mix outer layer moves with the shoe. The resulting lack of friction between the layers helps to prevent blisters and reduces wear. Furthermore the new HeelPower design grips the heel keeping the sock firmly in place. Ideal for 3 seasons walking in all types of boot, this sock contains Merino wool which is one of the softest types of wool and provides warmth without overheating the wearer and its moisture wicking properties combined with being slightly moisture repellent allow the wearer to remain dry.
