Trek Flames Fuel Sock S/M WhiteThe trek Fuel Sock has a crazy fuel logo with flames that ride up from the toes to the reinforced heal. Woven from 75 % microsupreme fabric (the rest is nylon/lycra), this sock wicks moisture like crazy. And as a result of the nylon and lycra, the socks are stretchy but very durable. Give your feet a treat and set them on fire with these sick cycling socks!745889153149
