INCYLENCE RENEWED 97 socks are made of 97% recycled yarns and fibers. The main component is ECONYL®, a regenerated nylon from ocean and industrial waste such as fishing nets, carpets and other waste products that exceeded their life time. Manufactured in Portugal these socks provide great comfort and breathability. Furthermore the strengthened parts under the foot, on the heel and at the toes, secure comfort and durability. The high-cut and double layered cuff absorbs sweat before streaming into the shoe and offers a pleasing tight fit without slipping. The thin workmanship on the instep provides large areas of breathable mesh, resulting in exceptional isolation. Due to compression in the midfoot area, the socks offer a perfect fit and surround the feet tightly. Extra padding at the toes and heel area provides superior cushioning and support and ensure durability.
