Mammut Alnasca Low GTX notable features

-The Mammut Alnasca Low GTX is built primarily for hikers-slash-climbers who wish to have a combination of lightness and precision in their step. Its board-lasted construction promises lasting comfort, ideal for extended approach trips.

-It comes with two Mammut-exclusive technologies: 360 Heel Support and Base Fit. The former is in the business of ensuring the ankle remains as locked in as possible. The latter, on the other hand, doubles down on comfort and security.

Size and fit

Mammut’s Alnasca Low GTX is a below-the-ankle approach shoe for men and women. It comes engineered with Memo Foam at the ankle, instep, and shin for a personalized fit over time. Owners can expect to have a snug heel fit in it, thanks to the 360 Heel Support technology. Its lace-up closure with Base Fit technology, on the other hand, provides a secure and customized lockdown.


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


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).

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.

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, a synthetic lace, and the Base Fit technology, which consists of a system of heel-hugging cords.
