100 mm Last – Cutaways in the bootboard: The Sensor 3 bootboard is narrow, so that the 3 contact points can be in direct contact with the boot's polycarbonate insert. The insert is very stiff, which increases the responsiveness of the boot.

Sensor Fit Liner – This focuses on solving all of the common problem fit areas. Sensor Fit simply fits more feet better.

One Piece Toe Box – No seams are on the front of the tongue, and the instep is very shaped and padded. This eliminates pressure points over the toes and instep.

Thermo Optisensor Fit Liner – This new liner, used in Pursuit Boots, gives better foot envelopment through better interaction between shell and liner. The thermoformable materials enables the boot to be customized to the individual skier's foot, for performance with comfort.

Sensor³ (Polyether + Polycarbonate Insert) – Using a narrower boot board that allows the three key receptor points to contact the poly-carbonate insert directly, the direct contact with the highly reactive poly-carbonate produces extraordinary power, control and feel.

Updated Cuff – An anatomical design provides better lower leg wrapping and enhances lateral power transfer.

Polycarbonate Insert – With an insert in rigid material, the cuff is very solid - backward support is excellent and rebounds are powerful. Fixed to the shell for increased boot responsiveness.

Double canting

Neutral Stance – Delivers more control, better balance and minimizes fatigue: Neutral Stance includes a laterally neutral cuff, 4.5 degree ramp angle and 14 degree forward lean.

Lateral spoiler

40 mm power strap

PU foam (hard) bootboard

Easy Entry – Notches in the plastic along the instep allow for easy entry and exit without compromising four buckle overlap boot performance.
