• Après Mode 2.0 – A new and improved walk mode offering a massive 50-degree range of motion. A lever on the back of the boot unlocks the upper cuff from the lower shell, allowing for increased comfort and convenience when walking from the car to the lift.

Buckles

• BOA® Fit System – The BOA® Fit System provides a performance fit engineered to enhance feel and responsiveness while reducing pressure points by incrementally modulating the Alpine boot closure with precise micro-adjustments.

In the unlikely event that the system is broken, it can be easily repaired and replaced.
