Alpine terrain and via ferrata are no problem with Aku Viaz GTX.
The Viaz GTX from Aku is suitable for demanding hikes and via ferrata. Reinforced where the strongest friction occurs and a comfortable fit characterize it. The Internal Midsole Systems (IMS) is a special construction of the inner sole. It combines a traditional nylon support structure with a layer of microporous material attached to the inside of the upper. In this model, the inner sole is complemented by another midsole made of thin microporous ethyl vinyl acetate. This allows the soles to adapt perfectly to the anatomy of your foot. And ensures even pressure distribution. The foot is prevented from slipping around in the shoe and still allows the foot to feel its surroundings precisely. So you never lose your stride. Since even a journey of a thousand miles begins with a single step, with the Aku Viaz GTX there is no longer any reason not to take that first step
