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.

Dedicated Women's Liners – Women's liners are cut lower to accommodate the female calf shape. They also have a more open shape for a more comfortable fit. The padding in the upper liner is very flexible to prevent any discomfort around the calf. The lining materials are very soft and comfortable, designed so you'll want to put your foot in 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.

Thinsulate® - Electra – The entire liner is equipped with Thinsulate® insulation.

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.

Dedicated Women's Cuff – The cuff height is significantly lower. The tulip-shaped rear section easily accommodates a woman's natural calf shape. The 2 cuff buckles are set lower for easy closure and better foot wrap.

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.

4 Diagnol Micro Buckles – 100% magnesium. Adjustable teeth 3 positions

Diagnol Buckles – Rossignol's patented buckles have angled bails and catches in a non-traditional diagonal direction for a more natural foot wrap and to hold the heel securely in place.

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.

F.I.T. (Feminine Intuitive Technology) – Tulip cuff, Thinsulate® insulation and large buckles address women's lower calf muscles, narrow heels, and a smaller forefoot shape and provide high performance without sacrificing warmth.
