This creates a high level of comfort for the wearer, even while performing strenuous and aerobic activities, while also preventing rain, mud, and sand from getting inside the sock Designed with a seamless construction including hand-linked flat toe seams and the addition of elastic support on the ankle, heel and instep, you won’t notice the seams but will definitely notice the extra comfort and fit 36%MerinoWool,36%Acrylic,18%Polyester,5%Nylon,5%Elastane Product Code: 11100061-
