We do not recommend it!
In recent years ski equipment has evolved enormously and new ski boots have arrived on the market. They offer an effective blend of stiffness, lightness and unmatched comfort.
Equipped with a walk mode, these ski boots allow you to untie the upper collar. They become as confortable as running shoes when it comes to hike up, but also when you have to walk from the parking lot to the ski lifts.
Most slackcountry ski boots are equipped with a front and rear insert compatible with low-tech bindings. The ski boots / binding combination saves a lot of weight.
We encourage you to adopt this modern ski equipment which will help your legs and your breath on the ascent, without impacting your pleasure on the descent.
If your ski ski boots are aging, don’t hesitate to buy slackcountry ski boots. They work as well for skiing in bound with family or friends as during a powder ski safari with the 9V guides.
