Rossignol Men's Alltrack 90 Alpine Boots

Regular fit features a 102mm last for a forgiving anatomical feel regardless of foot shape

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 boots in the ALLSPEED, ALLTRACK and PURE range are delivered with heelpieces conforming to the ISO 5355 alpine ski-boots standard. Heelpieces conforming to ISO 9523 (touring) and WTR standards are available in kit form. These rubber Rocker heelpieces make walking significantly easier through improved surface grip due to a natural foot roll. Their design also enables a very high level of skiability, with the rigid zones giving the boot added torsional strength. Two heelpiece kits are available - for boots with anti-slip soles and for boots without anti-slip soles.

Custom liners offer internal customization for enhanced comfort and support

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.

CUSTOM liners offer customization in the internal padding for enhanced foot wrapping and comfort. T4 version features mono-injected Polyethelene padding for a consistent soft density throughout performance and fit zones.

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.
