From scree fields to meadows, stony terrain or the iron stemples of a via ferrata route, the Alto Guide High GTX is a reliable and very comfortable companion in any terrain.

This high-cut mountain hiking boot combines a light weight with secure support. Clever details including an anatomically shaped heel cap, reinforced on the inside to prevent twisting of the ankle, help you feel safe even in demanding terrain. The Alto Guide High GTX incorporates the latest enhanced versions of proven technologies, such as Mammut’s patented Base-Fit system. The free-sliding doubled heel straps strengthen heel support by distributing the lines of force above and below the heel bone. This improves support in the boot, increases safety and comfort while at the same time reducing the risk of blisters. The inside of this mountain hiking boot is equally impressive. High-quality cushioning memo foam is incorporated in areas sensitive to pressure, such as the instep, shin and ankle, adapting ideally to the shape of the wearer’s foot. Thanks to its high resilience, it returns to its original shape even after intensive strain. The elastic GORE-TEX® tongue construction and Performance Comfort membrane keep your feet dry in these strap-on crampon compatible boots, even when perspiration starts to flow on strenuous ascents. The high-quality Vibram Maton sole, raised rubber rand and board lasting add the finishing touches to the Alto Guide High GTX. This stylish mountain hiking boot is available in either a men’s or a women’s version.
