Yaktrax Medium Pro Ice Cleat is designed for those with an active lifestyle who need reliable traction and safety while walking, jogging, or running on packed snow or ice. This innovative ice cleat provides 360 degrees of traction, allowing you to enjoy outdoor activities or maintain your athletic training with the same stability you experience on dry surfaces. Featuring a spikeless, ultra-lightweight design, it is built to last with 1.4mm high-strength, shaped edge steel coils that are abrasion resistant and made with 70% recycled content. The natural rubber webbing is brittle-resistant to -41 degrees Fahrenheit and has no memory, meaning it returns to its shape when removed from footwear. Its elasticity ensures ease of use when attaching to shoes, making it a practical and durable choice for winter traction. The medium size fits men's shoe sizes 9 to 11 and women's shoe sizes 10-1/2 to 12-1/2. Model Number: 08611
