Durable and aggressive 

This boot is powered by the Vibram Litebase - an innovative outsole that is as durable and aggressive as other Vibram mountaineering soles but is much thinner. Despite the substantial reduction in the thickness, it doesn’t change the depth, shape, and size of the lugs.

Excellent grip on different surfaces

The Taiss Light mid-top hiker has plenty of spaces between the lugs so no dirt or mud gets stuck in between. Also, the lugs are multidirectional so they grip well on different surfaces.

Long-lasting cushioning

The Taiss Light has a midsole made of a PU wedge. Among the different types of foam used in performance footwear, PU is one of the most durable. It's a highly resilient foam and unlike EVA, it doesn't compress over time. Thus, hiking boots and shoes with PU midsoles deliver long-lasting cushioning.

While PU is heavier than EVA, it doesn't make the Taiss Gore-Tex boots heavier as the heaviness of the midsole is offset by the lightness of the upper and sole.

Abrasion, wear, and tear-resistant

These boots have Schoeller softshell uppers made of durable fabric that is resistant to abrasion, wear, and tear.

The side panels are made of Ripstop and mesh, and inside the boot is a Gore-Tex waterproof membrane that protects against rain or water. The Mammut Taiss Light mid-top hiker doesn't have insulation so they are best worn as summer alpine boots. If trekking in cold weather, it's important to wear thick socks (preferably thermal socks) for added warmth and comfort.

Two-zone lacing system

The Taiss Mid is classified as a B2 boot which means it is compatible with semi-automatic crampons. Completing the upper is a two-zone lacing system that allows you to adjust the tightness between the lower foot and the ankle. Thus, you can loosen up the ankle when walking on city streets or well-established trails and cinch it up when traversing vertical terrain.
