- Snow grip & ground feel
- Less grip on paths
The ice and alpine touring boot with top fit and additional forefoot traction has a grippy sole with top front kick and super snow repellence in the snow. The shaft is very flexible. Precise on rock, but less grippy at the front

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.
