These ice cleats give your feet the traction you need to walk through the city with confidence in the icy winter weather. Whether you're at the dog park, strolling down city streets, or racing around an exterior set, these easy-on cleats will stop you from sliping in the snow (and the ice hidden under it), so you stay safe and your bum stays dry, all winter long. Not for use indoors, or while driving. Not suitable for climbing. Traction for walking on ice and snow. Durable and lightweight with 10 replaceable cleats. Easy to slip on and off. Slip the front of the ice cleat onto the front of your footwear then pull the heel to secure it in place - that easy!
