Safely tackle the most demanding winter hiking conditions in our most capable, adjustable and packable crampon. A folding heel support means KTS collapses down into a small package you can take anywhere, and an infinitely adjustable, independent front and rear binding system makes dialling in the perfect fit a breeze. For added comfort and range of motion, our patented LeafSpringA(R) Flex Bar technology, allows the ankle and foot to move independently. LeafspringA(R) Flexbar Technology - When used with flexible footwear, our unique, patented flex bar system moves with the foot to ensure a wide range of motion. 10 Independent 1 Inch Long Chromoly Steel Spikes - Our most aggressive spikes are strategically placed so they provide a very stable platform for walking, while tearing deep into hard ice and snow. Folding Heel Bail - Collapses down for maximum packability. Lightweight, Replaceable Snow Release Skins - These allow the snow buildup that often comes with warmer temperatures to clear itself from the bottom of the crampon. Independent Front and Rear Binding System - The KTS(TM) binding system is infinitely adjustable and allows the ankle and foot to flex naturally for maximum range of motion when used with flexible footwear.
