The 3.0 heel cup has a new & different shape in 4 areas to respect the natural flex of the ski and is shock-resistant. The front has been aerodynamically re-designed for hydrodynamic performances. A new release mechanism (840) with arms constructed of stainless steel. The shape of the release arms have also been designed more vertically to keep the heel strongly connected to the plate. It will be also good for skiers who like to keep their rear foot big toe near of the heel of their front shell.
