Alpine Performance
The Hy Free delivers the responsiveness, control, and confidence of an alpine binding. The boot sits flat on the ski in ski mode, eliminating the pin-height differential typical of standard PIN bindings for a true downhill experience.

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, we have 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. Thinner plastic soles provide a stiff connection with the binding. For this reason, we designed softer spacers that also serve to dampen vibrations. Thicker rubber soles require little to no spacers, as their rubber composition inherently provides vibration absorption.

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.

Negative Steps 
For uphill efficiency, the Hy Free includes a unique “negative” walk mode that allows the boot heel to drop slightly below the toe level. This reduces strain and improves stride efficiency, especially for freeride boots with limited cuff mobility and during long flat approaches.

Walking Modes 
The Hy also features two heel raisers for easier uphill progress, both activated easily even with the pole.

Hy Brake System 
The rear ski brake locks automatically when the heel piece is in walk mode. This means that when the real lever has been pushed fully forward the ski brake can be locked in position with a simple press of the rear paddle. When transitioning to ski mode, it seamlessly unlocks by pushing the rear lever backwards, ensuring hassle-free use.
