Key technology of Kästle Boots

K_RELEASE

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.
