evo.com | ATK Alpine Touring Ski Bindings > Backcountry skiers, meet your freedom machine. The ATK HY 13 Free Alpine Touring Ski Bindings deliver incredible downhill performance in a featherweight 675g package, shattering the traditional compromise between downhill power and uphill efficiency. Its ingenious design - an intuitive, easily adjustable toe piece, seamless transitions, and a unique negative walk mode with two heel raisers - transforms how you move through mountain terrain. These bindings promise total freedom in a single, meticulously engineered system that has your back from peak to parking lot. We recommend a brake width equal to or at most 15 mm wider than the ski waist width. Heel Clamps The heel clamps, inspired by the alpine system, offers a spectacular sense of control and precision. Boot Compatibility The Hy is compatible with most alpine skiing, ski mountaineering, and freeride boots. To ensure safe and high performance, the Anti Friction Device (AFD) slider on the toe piece must be adjusted with various sole types. To achieve this, ATK developed specific spacers that fit between the sliding section of the AFD and its underlying structure. These spacers ensure proper boot-to-binding contact while accounting for the sole's thickness. Seamless Transitions Switching between ascent and descent modes is effortless. Simply raise the toe arms for walking or rotate them forward and down for skiing. The intuitive design ensures reliable performance in all conditions with no needs for interchangeable parts. Flat Skiing In ski mode, the boot sits flat on the ski, eliminating the rear-front pin height differential typical of standard pin bindings. This design delivers an alpine-like feel and performance. | ATK HY 13 Free Alpine Touring Ski Bindings 2026 - 97 in White
