Excellent surface grip

The Alnasca Knit Low GTX approach shoe is equipped with the Michelin Rock Tech outsole for a 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.

Provides slip and skid resistance

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.

Comfortable and stable cushioning

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.

Easy to wear

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.

Breathable and waterproof

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.

Provides protection against abrasive hazards

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.

Secure lockdown

Its lace-up closure consists of 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.
