The Dual BOA® PerformFit. 
The Dual BOA® now works with the lower part of the boot (shell) and the top of the boot (cuff) to enclose the foot and the lower part of the shin. This provides a uniform fit that reduces pressure points on the top of the foot and keeps the heel securely in the heel pocket. Ski boots with BOA® technology improve power transfer from boot to ski by up to 6% and increase stability and control during turns by up to 10%.

Polyurethane (PU)
A consistent density material that wraps around the foot for a snug fit and provides reliable progressivity for controlled flex. It also allows for efficient power transmission and is resilient enough to withstand impact.

Custom tongue
A fully removable and fully customisable tongue that allows for precise instep height adjustment. You can add or remove material to customise the fit, allowing up to +/-8mm of adjustment for maximum comfort and support.

Custom Shell HD
The shell can be customized to the shape of your foot using heat. The thinner wall construction and materials ensure that the shell closely envelops your foot, resulting in enhanced sensitivity, control, and power transfer for a responsive, tailored skiing experience.

Exobelt technology
A combination of a plastic closure and the BOA® Fit System keeps the heel securely in place, reduces the risk of blisters during ascents, and provides precision and control during descents.

Custom Fit 4D
A pre-shaped liner is crafted to improve foot support and overall fit. Softer foams and the external positioning of the Talyn® material make it easier to customise, while the elasticated toe box provides extra room, improving comfort and allowing for a more personalised fit.
