Ergodyne - EGO16736 Trex 6300TC Slip-On Ice Cleats are lightweight ice grips for boots to prevent slip-and-fall injuries on the ice. With extremely durable studs, these ice cleats provide tenacious traction and extra stability on ice and snow. Tungsten carbide studs are stronger and thinner for better penetration and stronger grip. This very hard compound rates 9 on the Mohs scale for hardness, second only to a diamond. Enjoy full-foot traction from eight rugged 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. Stretchable rubber with textured interior hugs the toe and heel of your shoe or boot. Large thumb tabs on the heels allow easy on and off. 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. 2XLarge size fits U.S. men's footwear from 15 to 18.
