Durable mountain shoes for alpine challenges. The Viaz DFS GTX sets a new standard for versatile shoes suitable for technical and fast mountaineering, demanding hiking, and via ferratas. They are an evolution of the AKU predecessor model Viaz and feature Dynamic Fit technology, which allows the tension in the heel area to dynamically adjust to your steps, enhancing comfort and stability. The AKU Dual Fit System (DFS) technology enables you to change the fit between walking and climbing modes. The Vibram Croda Litebase sole provides stability, grip, and precision, even in the most technical situations. The waterproof, breathable GORE-TEX lining protects the feet from moisture and ensures a pleasant wearing climate.

Developed for alpine tours, the Aku Viaz DFS shines with maximum climbing performance and amazingly high wearing comfort. Thanks to the ultra-stiff but sensitive sole and snug-fitting shaft, you can climb the trickiest walls with dancing grace. The forefoot, which can be laced separately with a quick-release fastener, is also very impressive. Price: 350 euros.
