Last: 100 mm – Average width last suitable for most feet.

Easy Entry Insert – An insert made of more flexible material is included at the instep, making it easier to pull the boot on and off.

Flex: 100 – A medium stiff flex for advanced skiers looking for a performance flex.

Optisensor 3D Liner – Delivers a new level of optimized foot wrapping, protection, comfort and support.

Forefoot Thinsulate™ – This thermal insulation is tested as the warmest insulation on the market. As a very thin fiber, it does not affect the technical properties of the liner, but enables excellent foot envelopment for great skiability.

Sensor Grid – Improves shell wrapping and reduces boot weight while retaining high-performance torsional rigidity for power, precision and energy transmission.

Shell / Cuff – Polyurethane

Bootboard – Polyurethane

Posi-Block Technology – In ski mode, reinforced vertical ribs in the upper cuff lock upper and lower shells together, delivering unprecedented downhill performance. In hike mode, the lower shell's U-shaped profile in the rear allows maximum range-of-motion for comfortable hiking and walking.

100% Aluminum buckles – 3 teeth positions, microadjustable

Diagonal Buckles – These buckles have bails and catches angled in a diagonal direction, giving a more natural foot wrap and holding the heel securely in place. On Pro models the buckles are very slender with cutaways for added lightness. The lever is wide for high power closure and easy gripping.

Optional WTR Soles – New interchangeable rockered soles are available separately to deliver easier, more comfortable hiking and walking. This optional aftermarket sole is compatible with WTR and AT bindings only.
