Lightly cushioned for comfort, our Wool Blend Anklet Socks are designed for a long life on the trail. They're made with Responsible Wool Standard (RWS) wool certified by Control Union (TE-00052557). We blend RWS wool with nylon and spandex for excellent stretch and recovery that lasts the lifetime of the socks. The purchase of RWS-certified products demonstrates demand for better animal welfare practices and responsible land management in the wool supply chain.
