The Yaktrax Pro is a more durable version of the Walker series. The spikeless design makes them comfortable to wear and the removable performance strap helps keep the Pro in place during rigorous use. The SkidLock coil system stays snugly with your shoe, offering unhindered ease of movement. The coils are hand wound in alternating directions to provide maximum 360-degree slip resistance on snow and ice. The more rigorous design of the Pro makes it the perfect choice for demanding winter use with postal, construction, safety, and highway workers. These are also great for runners, hikers, and the more active recreational winter athlete.
