The Alnasca Low GTX is an astonishing piece of Mammut gear—one that looks as good as it performs. It is a solid option if you:

Provides slip and skid resistance

The Alnasca Low GTX’s provision of slip and skid resistance comes from its Michelin Rock Tech outsole. It offers multi-directional traction with its low-profile lugs.

Excellent toe-gripping performance

Mammut gave it a treaded climbing zone that grants hikers added grip when toeing over boulder-type surfaces. They also furnished it with a heel brake for extra descent control.

Provides stability and cushy underfoot 

With its Dual-Tech midsole, this approach-centric shoe from Mammut gets to supply users with enough stability and cushioning underfoot. It has a dual-density construction, which delivers zonal comfort, especially during transitions. The rear region of this cushy component comes with a heel stabilizer made of TPU (thermoplastic polyurethane).

Supportive and comfortable footbed

Rounding out all things midsole in the Alnasca Low GTX is its anatomically shaped insole. Aside from added cushioning, this subcomponent also grants additional support.

What wraps the foot in the Alnasca Low GTX is the hiker’s partly textile, partly velours leather upper. Its plush bootie is engineered with Gore-Tex’s Extended Comfort liner, making the shoe capable of fencing out intrusive wet elements while allowing moisture to wick out from the inside.

A rubber toe cap takes point in this shoe, delivering abrasion protection and extra toeing traction at the same time. The upper’s heel, on the other hand, is furnished with a TPU plating (a.k.a. the 360 Heel Support), which further reinforces the shoe’s rear zone.

Snug fit

Making the Mammut Alnasca Low GTX’s upper come full circle is the shoe’s fit management system. It is made up of combination eyelets, synthetic lace, and the Base Fit technology, which consists of a system of heel-hugging cords.
