dri-release® Wool and NanoGlide® combine together to provide a super soft and comfortable feel to one of the world's most technical running socks. The dri-release® Wool is not just soft but is also high wicking and anti-microbial keeping feet dry and fresh. The NanoGlide® in the heel and toe helps prevent blister from appearing by minimising friction. Extra cushioning is placed into key impact zones under the heel and toes.
