The NX 11 GripWalk(R) binding is a user-friendly all-mountain binding for recreational skiers. Its lightweight toe piece and NX heel work together to deliver strong power transmission and fluid shock absorption with an easy step-in design. The Full Drive Concept toe design allows upward release independent of the heel for the most dynamic release in the event of a fall. The binding's overall lightweight construction makes skiing and carrying skis easier. It's compatible with adult ISO 5355 and GripWalk(R) ISO 23223 A boot soles.
