Ultra-thin and lightweight design for an undisturbed feel while worn. The front protects the instep from irritation. Internal non-slip silicone grips on the back of the heel help prevent the socks from slipping. The material wicks away sweat and dries very quickly. Mesh panels on the forefoot for added breathability. Built-in arch support reduces foot fatigue. A tailored heel wraps around the foot for a better fit. 3 pairs of socks.
