The design of the ONYX binding is focused on the best combination of lightweight, high performance, and usability. G3 stayed true to their commitment to lightweight by designing an enhanced Tech system toe attachment that provides a rigid and secure boot interface, an easy step-in experience, and a high level of retention. They then added a heel mechanism that shifts fore and aft to allow for an easy switch between ski and tour mode without having to release the boot from the binding. Finally, they added an easy to adjust mounting plate system so that one mount fits multiple boot sizes.
