The TREX 6315 Strap-On Heel Traction Cleats are ice grips for boots and shoes with rugged steel plates that turn boot heels into ice picks, leaving the mid-foot free for vehicle operation or climbing ladders in cold conditions. The channel steel plate design will not retain ice, snow, or debris making the heel traction cleat versatile for hiking, running, construction, roofing, road work, ice fishing and for delivery service workers.
