Thank you for viewing. Yaktrax Pro instantly provides confidence and safety on snow and ice. You'll feel the solid grip you're familiar with on dry surfaces. Yaktrax Pro is made with a natural rubber blend for durability. It also comes with removable performance straps to keep the Yaktrax in place while in use. Yaktrax Pro is suitable for walking, recreation, and industrial sites. Use it anywhere stability on snow and ice is required. Please refer to the table below for correct sizing information. I will ship it after taking it out of the box.
