Whether it's a narrow channel or a steep north face - with the Blacklight, speed climbers can master even the most challenging terrain with ease. The low weight and generous cuff rotation make the boot the ideal companion for long tours. Instead of a conventional tongue construction, the Blacklight has an innovative tech gaiter that protects against the cold and the wind and guarantees a perfect fit. The patented Hoji Lock System shows its strengths in downhill mode: The boot shell and liner become a completely interlocking unit without any play to provide optimal power transmission.
