Yaktrax Pro Plus Traction Cleats utilize durable steel coil technology to add grip to winter boots and shoes when traversing icy surfaces and snow-covered terrain. The unique coil design grips into surfaces in all directions for added walking grip and lateral stability, and is also springy for a comfortable feel underfoot that won't inhibit your natural stride when walking and hiking. The thermoplastic rubber upper with an integrated heel tab remains flexible even amidst freezing conditions, so it's easy to install over most footwear yet remains securely in place. An adjustable over foot strap helps provide an even more secure, customizable fit with your favorite winter boots and shoes. The unique coil design wraps around the underside of the harness, helping protect it from abrasions and damage. The Pro Plus comes with a carry bag and carabiner, so you can conveniently store it inside a bag, purse, or glove box, or attached to a pack or luggage, so it's always ready to enhance your footwear's grip whenever you're faced with challenging winter conditions.
