As an entry-level model for hiking in high alpine regions and on developed paths, 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 allows for a perfect fit to the foot. The free-running Speedwire of the variofix® system wraps evenly snug 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.
