Ski race is the aluminum crampon for ski mountaineers. We find the innovation in its ski matic 2.0 binding, which closes comfortably on the front of the ski boot (making the operation much more comfortable) and does not interfere with the rear walk / ski systems of the boots. The central bar allows adjustment. Light and practical for those who practice ski mountaineering.
