Here are the images of a wave of 1500m in a very alpine terrain and very steep sections. An already serious descent on ski or snowboard. So doing it without bindings was a good challenge. Thanks to @schuminator20 for giving us the motivation and for believing in our ability to ride this run on a Powdersurf. Thanks to @manu_gross for demining and his enormous experience in the mountains which allowed us to concentrate on the descent. And thank you to @kurthmanuel for his good vibe, which gave us some relaxation. Powsurfer: Didier Balzaretti and Olivier''Milon''Favre
