AKU Viaz DFS GTX

"The Viaz DFS GTX from AKU sets new standards for versatile shoes that are suitable for technical and fast mountaineering as well as demanding hikes and via ferratas. Based on the historic AKU Viaz model, this shoe offers a perfect symbiosis of comfort and stability thanks to the innovative Dynamic Fittechnology. This makes it possible to dynamically adjust the tension in the heel area to your stride, which is particularly beneficial on longer hikes or when climbing"
"An outstanding feature of the Viaz DFS GTX is the exclusive AKU Dual Fit System (DFS), which allows you to switch the fit between walking and climbing mode. This ensures optimal adaptation to the respective activity, be it approaching, mountaineering or climbing on demanding routes. The Vibram Croda Litebase sole ensures excellent grip, stability and precision even in the most technically demanding situations and is compatible with traditional or semi-automatic crampons."
"The shoe is made of robust nylon and is waterproof, which makes it ideal for all weather conditions. The 130 cm long laces allow for an individual fit, while the AKU Elica Natural Stride System increases biodynamic performance by promoting a natural walking motion. The Viaz DFS GTX is the perfect companion for men who feel at home in the mountains and don't want to compromise on equipment."
