Trex 6310 Adjustable Slip-On Ice Cleats are lightweight ice grips for boots to prevent slip-and-fall injuries on the ice. With 10 replaceable spike grips, these ice cleats provide tenacious traction and extra stability on ice and snow. Stretchable rubber with textured interior hugs the toe and heel of your shoe or boot. Enjoy full-foot traction from rugged, heat-treated, carbon steel studs that line the length of the foot with a thicker, under-sole tread and a reinforced toe cap for more durable wear and better grip. Large thumb tabs on the heels allow easy on and off. Adjustable cord cinches tight for a secure fit. One-piece, reliable cleats are flexible in temperatures as low as negative 40 degrees Fahrenheit (negative 40 degrees Celsius) and won’t break in cold temperatures. They are compact so cleats are easy to store. Medium fits U.S. men’s boots in sizes 5 through 8.
