Voile Universal Ski Crampons provide ultimate security for backcountry ascents. Unlike mobile systems that are specific to certain binding systems and only provide minimal purchase into the snow while the heel elevator is in the up position, Voile Universal Ski Crampons are designed to work with most telemark bindings and are fixed to the ski to always provide full purchase into the snow even with the heel elevator in the up position. Available in 3 widths, up to 96mm ski waist, up to 115mm ski waist, and up to 130mm ski waist.
