Shell Technology:

• Narrow last
  Ski boots with a narrow last have a width of 98mm or less at 26.0/26.5. This fit is designed for slimmer feet and provides a snug and precise feel. 

• 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 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.

• BOA system
  The BOA system offers a micro-adjustable, precision fit, utilizing stainless steel cables and low-friction lace guides. This system provides optimal foot wrapping and enhanced shell wrapping with bi-directional adjustments via the BOA Fit System Alpine’s platform, ensuring a secure, customized fit that improves heel hold and edge control.

• 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.

• Gripwalk
  Gripwalk ski boot technology is designed for greater safety while walking. There were simply too many accidents. Therefore, the heel and toe pieces now have much more grip by using a softer compound rubber combined with a coarser profile, ensuring a lot less accidents. 

• Tech inserts
  Metal fittings built into the ski boot shell that securely engage with touring bindings. They ensure efficient power transfer and enhanced stability during uphill ascents. Essential for backcountry and touring skiers, these inserts offer reliable performance and precise control across challenging and varied terrain.

Cuff Technology:

• Frictionless pivots
  The pivots points are designed to allow the cuff to rotate smoothly and naturally, facilitating upward movement and reducing drag, which is particularly beneficial on long ascents.

• Freespine
  A strong plastic spine at the back of the boot connects the cuff to the lower shell, increasing support and stability on both ascents and descents. This durable structure ensures a secure fit while maintaining the boot's performance in a variety of alpine conditions.

• Twinlock mechanism
  A system that allows a wide range of motion when walking and a progressive alpine flex when skiing. The horizontal closure position is designed with safety and durability in mind, ensuring the boot remains secure and stable in all conditions.
