Explore our Boot Technologies.


The ultra-flat aluminum buckles are ergonomically adapted to the boot shell and therefore allow for sharper edge angles in extremely steep terrain. A specially developed release mechanism ensures effortless unlocking of the buckle, thanks to the flash-opening. Furthermore, we also focus on safety without compromising performance: with minimized surface area there is less risk of opening or damaging the buckle due to external influences.


Power control thanks to step-by-step release.
The power strap of our K_Boot can be loosened or tightened gradually. Thus, it’s easy to find the optimal setting and the ideal support for intense responsiveness and exceptional power in every turn.


Kästle's secret material mix.
Outstanding performance results from a constant pursuit of innovative solutions. For the creation of our K_Boot, we use an extremely specialized material for our top models. "Kästle's secret mix," if you will. The answer from our R&D department for better skiing experiences in all conditions.


Adaptable spoiler for more control.
The use of a separate spoiler guarantees more efficiency and control when skiing. Easily attached to the liner thanks to Velcro, it increases rear support and allows the skier to customize their forward lean.
