The Triple Pivot Light Toe and Hollow Linkage Heel make the binding compact as well as sturdy. Its SOLE.ID technology allows the shop to adjust the binding to accommodate either AT or Alpine boot sole norms. This gives the skier the ultimate flexibility, and allows them to choose a boot with easy to walk soles like GripWalk, to make it easier and (and more fun!) to walk in ski boots. Available in 3 color combinations.
