RUTHERFORD TOE COVERS SKINSSnug fitting anti blister toe covers. Rutherford's newest toe cover is marginally thicker (. 087mm) than the ultrathin material, but is considerably softer and has much more stretch. It also has a microfiber interior (logo goes on the outside) which feels like silk against your skin. The new skins material also provides a bit more padding than the current ultrathin material, yet takes up no more room. The light gray color disappears under a sock.
