Waterproof and comfortable trekking shoe for medium-difficulty tours, featuring a grippy Vibram sole and innovative technologies.
With the Alterra II GTX from Aku, you don't always have to walk in the middle of the trail, yet the shoe feels most comfortable on medium-difficulty, medium-length tours in mixed terrain.
To keep your feet dry even in the rain or when crossing rivers, the hiking boots are equipped with the proven and waterproof GORE-TEX® More Seasons technology. This is integrated into the shoe and ensures optimized breathability. Sweat in the form of water vapor can escape to the outside so that you feel comfortable in your shoes at any time of year and in any weather.
In addition, the upper material made with the AKU AIR 8000 system has up to 11.5 times higher breathability compared to other GORE-TEX® shoes.
The Vibram sole is known for its outstanding grip and stability on a wide variety of underground surfaces. It offers maximum safety and impresses with its high durability.
In combination with the Internal Midsole System (IMS3), the exoskeleton framework, in which the midsole consists of an outer skeleton made of polyurethane and is raised at the rear to surround and protect the heel, ensures optimum support and stability when walking. The asymmetrical structure, with a wider inner part and a polyurethane elevation, provides support to the midfoot while preventing overload and thus pronation.
The Elica system ensures unique comfort. It replicates the shape of the sole of the foot, supports the normal inclination of the heel and forefoot and thus reduces impact and strain. The asymmetrical lacing system, combined with the tongue made from GORE-TEX® stretch fabric, ensures a good fit and optimum comfort.
With the Alterra II GTX from Aku, trails become playgrounds and climbs become adventures. So lace up and off you go - the next adventure is already waiting!
