The BOA® Alpine single-dial shell configuration delivers a micro-adjustable, multi-directional, precision fit that locks in the heel to deliver improved power transfer, stability, and control. BOA® is engineered and guaranteed to perform.

The shell has longer panels upwards along the shin for two main reasons:

Easier step in: higher panels allow the shell to be spread out with the hands and slide nimbly into the boot even in the coldest temperatures

Immediate power transmission: the shell is also connected to your shin and not just to the foot. This significantly improves the immediacy of impulse transmission from the skier to the equipment.

The mechanism partially frees the cuff from the shell allowing more natural walking.

A new revolutionary technology allows us to attend the anatomical details of the tongue along its entire length. Memory foam inserts ensure the best adaptability, and the foam thickness is already adjusted on the instep for better three-dimensionality.

The 'Ankle Sense' padding features an asymmetric and pre-shaped design, specifically crafted to improve responsiveness with the BOA system. It provides better lateral sensitivity through the use of rigid, preformed padding, improved heel hold thanks to its ergonomic shape, and optimal interaction with the pressure from the lacing system.
