Double layered with a warm, wool rich outer and soft, smooth breathable Tactel inner, the 1000 Mile Ultimate Heavyweight Walking Sock is designed to help reduce friction on the skin during activity, helping to prevent blisters. While the moisture-wicking Tactel inner moves along with the foot, the wool blend outer layer moves with your footwear, reducing friction between the two. A chunky style gives the volume needed to fill a traditional walking boot. A broad ribbed leg and arch bracing further improves fit and hold on the foot. This men’s fit walking sock is thick, durable and insulating, suitable for wearing right through the year, and across all four seasons.
