Anti-friction zones (zones that reduce friction) in the heel and toe area prevent painful blisters. Our low-cut running socks also feature a heel tab, which results in an additional layer of fabric that rises to protect the area between the back of the ankle and the shoe. The material is treated with OEKO-TEX certification to ensure that these socks do not contain harmful substances. Material: 80% polyamide (recycled) 17% polyester 3% elastane
