The SockGuy SGX NICA Sock is a 6 inch cycling sock for any ride, with a design inspired by youth cycling teams and the community that riding builds. Double-stitched nylon reinforces the heel and toe, and a polypro base wicks moisture away from the foot. What Our Gearhead(R) Experts Are Saying:"The cuff stays where I put it for an entire ride, and my feet run cooler on long climbs because the mesh on top keeps air moving."
