Product details
The Aku Viaz GTX is designed for demanding hikes and via ferratas. It is reinforced in areas of highest friction and features a comfortable fit. The Internal Midsole System (IMS) is a special construction of the insole. Here, traditional support structures made of nylon are combined with a layer of microporous material, which is attached to the inside of the upper shoe. In this model, the insole is complemented by an additional midsole made of thin microporous ethylene-vinyl acetate. This allows the sole to perfectly adapt to the anatomy of your foot, ensuring even pressure distribution. It prevents your foot from sliding inside the shoe while still allowing for precise feedback from the ground. This way, you will never lose your footing. Since a journey of a thousand miles begins with a single step, there is no reason not to take that first step with the Aku Viaz GTX.
