The first of two systems developed by AKU to guarantee a high level of shoe breathability. Its a specially-made technical material that increases breathability over 24 hours by over 11 times when compared to conventionally-made material.
- Internal Midsole System
An exclusive technology used in the AKU footbed base construction. It unites the traditional nylon support structure with a layer of microporous material. This system enables the sole to fit perfectly to the shape of the foot, guaranteeing an even distribution of impact for excellent comfort.
- Vibram sole
Most of the AKU collection uses exclusive Vibram soles, both for the design and the specific shape of the sole, as well as the leather used in their making. The outsole is also designed for the specific needs and end use of the shoes. They have designed 3 different types of sole for mountain, trekking and active that have a particular abrasion-resistance.
The GORE-TEX membrane is an exclusive technical insulating material that contains around 1.4 billion microscopic pores per square centimetre. These pores are approximately 20,000 times smaller than a drop of water, but 700 times larger than a water vapour molecule. That way, water drops cant penetrate the membrane and water vapour can escape easily. GORE-TEX has designed 3 specific types of membrane for the footwear industry, each with specific functions.
Quick OverviewThese highly technical AKU boots have a perfectly refined style, and the lining will keep you protected on any high-altitude adventure.
