AKU Superalp NBK GTX – Built for Multi-Day Backpacking

AKU Superalp NBK GTX is designed for multi-day routes at high altitude and backpackers covering long distances with heavy loads. It provides the support, cushioning and stability required for demanding terrain and extended periods of walking.

AKU describes the Superalp NBK GTX as a reliable boot designed to maintain comfort and protection even on rough terrain after many hours of continuous use.

2.6 mm Nubuck Leather Upper

The upper is made from substantial 2.6 mm Nubuck leather sourced from Italian tanneries. AKU highlights its exceptional robustness and a fit that becomes progressively more comfortable with use.

A protective rubber rand surrounds the lower section of the boot to provide additional protection from rocks and abrasion.

GORE-TEX® Performance Comfort

The GORE-TEX® Performance Comfort lining provides weather protection for demanding trekking and backpacking use.

Exoskeleton and Dual-Density PU Midsole

The PU wedge uses AKU's Exoskeleton construction, designed to deliver optimal cushioning, high shock absorption and excellent stability.

The dual-density PU midsole provides the support required when travelling over rough terrain with a heavy backpack.

Vibram® Fourà Outsole

The Vibram® Fourà outsole is designed for dependable traction and stability across demanding mountain and trekking terrain.

Stiff Support Platform

The lasting board combines 6–4 mm nylon, 10% carbon fibre and die-cut EVA. AKU classifies the construction as STIFF, providing substantial support during demanding backpacking trips.

Advanced Lacing System

The pulley lacing system allows pressure to be distributed more evenly across the forefoot, while lower lace locks allow the upper section of the boot to be adjusted independently.
