Rossignol Alltrack Pro 90 GW W Ski Boots

Rossignol say - Free yourself to explore the mountains, the woMen's Alltrack Pro 90 GW is designed to ski the whole mountain. A releasable cuff offers a natural range of motion for hiking and a 100mm last balances comfort and control. The Generative Design Grid shell is engineered for reduced weight and full power transmission in all-conditions and terrain. The full custom liner includes Thinsulate™ for added warmth and is thermo-moldable for a precise fit.

GENERATIVE DESIGN GRID - A progressive new data-driven design approach that harnesses the power of generative design software to create the ideal boot shape. Focused on minimizing shell wall thickness for reduced weight while simultaneously enhancing power and support, our new GENERATIVE DESIGN GRID shell offers the most effective blend of both.

DUAL CORE TECHNOLOGY - Our new "power injection" method allows the simultaneous injection of two different durometers of plastic at the exact same time. This unique mono-injection process allows targeted power transmission and shell wrapping; and creates our DUAL CORE sandwich construction throughout the shell, resulting in livelier rebound, response, and total control through the turn.

HIKE MODE 2.0 - The new OPTIMIZED HIKE MODE includes a wider opening in the back of the lower shell, and a lower axis-of-rotation for optimized range-of-motion and uphill mobility (50⁰ ROM). The articulating lower shell insert and metal-on-metal locking mechanism increase rearward support while supplying maximum power transmission on descents.

FULL CUSTOM T2 - FULL CUSTOM liners offer customization both in the internal padding for enhanced foot wrapping and comfort, and the external liner materials for enhanced precision and power transmission. T2 version features two separate bi-injected zones w medium density EVA padding in the performance zones and soft density EVA padding in the fit zones.

THINSULATE STRETCH - Developed by 3M, THINSULATE® is a lightweight synthetic insulation that delivers increased warmth in damp and cold conditions for all-day comfort and warmth. THINSULATE® STRETCH offers enhanced elasticity, improving freedom of movement and foot support for better skiability.

DEDICATED WOMen's CUFF - Featuring a shorter upper cuff and open, tulip shape on the rear of the liner, the WOMENS CUFF accommodates a woman's natural calf shape for increased balance, comfort, and performance.

SLIM FIT - Our women-specific 100mm "medium" last, SLIM FIT is perfect for proficient women skiers seeking a strong balance of comfort and support.
