Who should buy the Aku Superalp GTX
The Aku Superalp GTX is a well-built high-cut backpacking boot crafted for day hikes and multi-day adventures. It's a reliable option if you need:
- a light yet stable hiking boot offering a sure grip and traction on various types of terrain
- a breathable and waterproof footgear that ensures a dry and fresh backpacking adventure
- a backpacking boot providing good cushioning and comfort for longer tours with heavy loads
Vibram's optimal traction
The Vibram Foura outsole is designed to give Superalp GTX users traction over uneven ground. It is a component-based on Vibram’s very own Megagrip rubber compound which balances ground stability and flexibility within a durable, overall construction.
The lugs on the front end of the heel and the concave dome of the arch also give the boot a heel brake—a part that assists users when tackling steep descents.
Extra protection in the forefoot zone
This Vibram outsole has an extended front profile, covering about a half-inch of the upper’s rubberized toe box. This extension veers away from the outsole’s primary purpose of granting surface traction, but further protects the forefoot zone instead.
Scarpa's premium support and cushioning
The Aku Superalp GTX depends on its cushy yet resilient midsole for underfoot comfort and stability. It is made of dual-density PU from which the midsole’s shock absorption, stress resistance, and long-term durability are sourced.
The frame that reinforces and adds extra support to the boot called Exoskeleton is also made of PU. This component acts as a shank that supports wearers when performing lateral and twisting maneuvers.
Moisture-wicking footbed
Doubling down on comfort is the Superalp GTX’s Custom Fit IMS 162 footbed. It is a part latex, part felt, removable insert that lends the boot a level of breathability and manages moisture for a dry and airy backpacking experience.
Breathable upper in Aku Superalp GTX
The primary protective coverage of the Aku Superalp GTX is chiefly made of suede leather. It is seamed at the ankle area to promote overall mobility.
The engineers imbued the upper with the Air 8000 technology which is a 1.8-mm thick layer consisting of a breathable textile on a sturdy, fiber-like backing.
360° protection
Within the bootie of the Superalp GTX is the Gore-Tex Performance Comfort liner—a membrane that is both waterproof and breathable. There is also a rubber rand running across the entirety of the upper’s base for scuff and abrasion protection.
Scarpa's secure fit
Securing the boot’s closure system are round laces. They are made up of interlaced synthetic cords. They pass through a series of lace tunnels and metallic open hooks from the toe box to the ankle collar. There is also a synthetic pull tab located at the flap of the tongue.
