As an entry-level model for hiking in high alpine regions and on developed trails, the Air Revolution 1.5 impresses with its Air Revolution® technology. The tongue is open at the top so that fresh air is sucked into the shoe during the tread phase and warm air is pressed out of the shoe during the push-off phase. The two-zone lacing, which is pulled far forwards, enables a perfect fit to the foot. The free-running Speedwire of the variofix® system tightens evenly around the heel and thus offers the best hold in the shoe. The Vibram® cleats-grip sole offers grip and a secure hold thanks to its special profile. Thanks to GORE-TEX, your feet are also guaranteed to stay dry.
