Mammut Alnasca Knit Low GTX notable features

-The board-lasted Mammut Alnasca Knit Low GTX is designed to provide a comfortable and secure ride over mountainous terrain in shifting weather conditions. Arguably, a good chunk of its provision of comfort comes from its knitted sock construction.

-It sports a sole unit courtesy of Michelin and a liner from Gore-Tex. The former delivers surefootedness on a variety of surfaces, while the latter grants the wearer adequate moisture protection.

Size and fit

Mammut Alnasca Knit Low GTX size and fit

A below-the-ankle approach shoe for men and women is the Mammut Alnasca Knit Low GTX. It promises a locked-in heel fit with its 360 Heel Support system. Its knitted sock construction delivers an almost seamless feel within its confines. Outdoorsy folks can get a personalized lockdown in it by means of the hiker’s lace-up closure with Base Fit technology.


The Alnasca Knit Low GTX approach shoe is equipped with the Michelin Rock Tech outsole for multi-directional surface grip. It uses Michelin’s OCX Approach rubber compound. As it comes with a number of low-profile lugs (a.k.a. studs), it is capable of latching on to loose soil with sufficient tenacity.

It features a climbing zone and a moderate heel brake. The former—that treaded front end—provides users with extra slip and skid resistance, particularly on smears. The latter, on the other hand, delivers additional stopping power on descents.


When it comes to underfoot cushioning, wearers have the Alnasca Knit Low GTX’s Dual Tech midsole to thank. As its name implies, it has a dual-density construction, which promises a blend of comfort and stability over rocky terrain. Mammut engineers furnished it with a heel stabilizer made of thermoplastic polyurethane or TPU. They also paired it with an anatomically shaped footbed for added comfort.


The Mammut Alnasca Knit Low GTX shields the foot from the direct assaults of the terrain with its mostly knit fabric upper. It comes with two pull loops (one at the heel and another at the tongue) for easy on and off. Its main bootie is imbued with Gore-Tex’s Performance Comfort technology, rendering the shoe adequately breathable and watertight at the same time. Its elastic tongue is also powered by Gore-Tex for increased moisture protection.

Reinforcing its rear zone is the technology called 360 Heel Support. It is a three-dimensional plating made of TPU. Its presence delivers extra heel support and additional protection against abrasive hazards.

Its lace-up closure consists of a cord-like synthetic lace and combination eyelets. This lockdown system comes with the Base Fit technology, which is a system of cords that can give the heel a tighter hug.
