Rossignol Alltrack 70 Alpine Boots

Women's-specific regular fit features a 102mm last for recreational skiing and all-day comfort

Generative Design Grid minimizes boot wall thickness for the most effective use of material to reduce weight and enhance power transfer

Dual Core technology provides targeted power transmission and shell wrapping, resulting in livelier rebound, response and control

The lower boot shell is designed to offer a 50-degree range of motion in walk mode for efficient touring and maximum power for skiing when in ski mode

The shorter, tulip-shaped cuff eliminates pressure around the shin and calf muscle for increased comfort and performance

Full custom liners are 100% customizable for enhanced comfort, precision and performance

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.

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.

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.

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.

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 (50° ROM). The articulating lower shell insert and metal-on-metal locking mechanism increase rearward support while supplying maximum power transmission on descents.
