Ergodyne - EGO16785 Trex 6304 Step-in Ice Cleats are lightweight ice grips for boots and shoes that provide tenacious traction and extra stability on ice and snow. Contoured, "step in," 3D design easily wraps around boots and shoes for a superior fit. Stretchable rubber with textured interior hugs the toe and heel of your shoe or boot. Enjoy full-foot traction with 12 rugged, heat-treated, carbon steel studs along the length of the foot for added stability and slip protection. Thumb tabs on the toe and 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. They are even small enough to be stored in a pocket or pack when not in use. XLarge cleats fit U.S. men's shoes and boots in sizes 11 to 14.
