The weight of the Vibram Sagarmatha sole has been reduced as much as possible, which means less energy is expended when wearing it. The thickness of the rubber is reduced on the front part of the foot and the heel and the two parts are separated by a zone without any rubber to lighten the sole even more. The innovative design stands out for its self-cleaning form and its outward grooves that facilitate the expulsion of snow. The choice of Vibram Snow rubber, specific for winter sports, improves safety, even without skis, thanks to its grip and resistance to changes in temperature and terrain.
