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, allowing fresh air to be drawn into the shoe during the landing phase and warm air to be expelled during the push-off phase. The extended two-zone lacing system enables a perfect fit to the foot. The free-running Speedwire of the variofix system wraps evenly around the heel, providing excellent support in the shoe. The Vibram Cleats Grip sole offers traction and secure grip thanks to its special profile. With GORE-TEX, your feet are guaranteed to stay dry.
