Very good100/100

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.
