The Alp Trainer 2 is a progressive hiking boot with a mid-cut upper, a rugged, premium suede and stretch upper, and a waterproof, breathable GORE-TEX® Extended Comfort lining that provides you with reliable protection on a variety of terrain and in changeable conditions. A generous rubber rand provides additional protection from rock edges and scree. The shoe offers a precise fit, encloses your foot securely, gives it support and is comfortable right from the first time you put it on. SALEWA's proprietary, patented 3F System incorporates a steel cable and provides firm ankle support and lateral stability, while the Flex Collar gives the ankle more room to move backward and increases comfort on descents. In addition, the customizable SALEWA® Multi Fit Footbed Plus (MFF+) lets you choose between different insoles to tailor the shoe volume to you. The climbing shoe lacing system also allows for individual tightening all the way to the toes - for better performance on technical terrain. The optimized Vibram® Alpine Hiking outsole, offered only by SALEWA®, improves performance and control on a wide variety of mountain terrain. Its special climbing, grip and braking zones and aggressive lug design make it convincing even in wet and muddy conditions.
