Meindl Ontario Blue Shoes Description: The AIR-ACTIVE technology that MEINDL first studied, developed and finally applied to mountaineering shoes, is the reason that makes Meindl shoes stand out in comfort and safety, especially in difficult and rocky areas, where every step allows the Meindl aerosols to completely absorb the vibrations from the impacts, first received by the sole of the foot and finally by our waist. AIR ACTIVE technology is a combination of foam material with intermediate closed cells, air tunnels for complete shock absorption and better balance, patented by MEINDL Exterior / Main Material Suede / Mesh Clima Interior / Lining Air-Active bottom Meindl Magic Active sole
