Provides slip and skid resistance

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 onto loose soil with sufficient tenacity.

Excellent surface grip

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 delivers 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 Tongue Pull Loop shields the foot from the direct assaults of the terrain with its mostly knit fabric upper. It comes with two pull loops (uniform at the heel and another at the tongue) for easy on and off.

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.
