Ski boots - Women -
The Alltrack 90 Boa is a women's ski boot developed by the brand Rossignol. It is the widest version in the Alltrack range with a last of 102mm, designed for skiers with wide feet who need extra comfort.
This boot has been designed to venture out on any type of snow. Equipped with a flex of 90, it provides good power transmission while remaining relatively forgiving and accessible, especially since its Boa adjustment system is very precise without restricting the foot.
It features the Generative Design Grid technology, which combines ultra-thin walls for minimal weight with increased power and support.
The Dual Core technology reduces the boot’s weight during approach walking while maintaining its stiffness for the descent, optimising its performance level. It also improves lateral transmission for optimal efficiency.
Finally, you will find a Mode Hike offering a wide range of motion of 50°, particularly useful for short approach walks. Additionally, its GripWalk endpieces will enhance this walking ease.
Thus, the Alltrack 90 Boa is aimed at competent skiers who want comfort, lightness, precision, and efficiency all in one boot!


Composition:
- Polyurethane shell
- Polyolefin cuff
- Aluminium buckles
| DUAL CORE | The Dual Core technology has proven itself on HERO World Cup boots, where efficiency is the ultimate rule. Adapted for Free touring boots, this technology reinforces the lower structure of the boot in flexion and torsion to guarantee skiability, while maintaining an unrivalled progressive flex. |
| GENERATIVE DESIGN GRID | An innovative data-driven design that harnesses the power of generative design software to create the ideal boot shape. The new Generative Design Grid shell perfectly combines ultra-thin walls for minimal weight with increased power and support. |
| BOA | Boa® adjustable systems delicately distribute pressure for all-day comfort without adding weight to your gear. |
| HIKE MODE | - An optimised rotation axis – 6 mm lower than on an ALLTRACK boot. - A new lower shell construction with a deeper cut at the rear, a wider opening of the cuff towards the back – range of motion > 50° for great freedom of movement when climbing. - A metal/metal cuff unlocking mechanism for greater rigidity in the boot’s structure. This design allows for high flex ratings and the performance level of a fixed-cuff boot. |
| THINSULATE® STRETCH |
3M Thinsulate® is a lightweight synthetic insulation that offers increased warmth in cold, damp conditions for all-day comfort and heat retention. Thinsulate® Stretch provides enhanced elasticity, improving freedom of movement and foot support for better skiability. |
| GRIP WALK | A sole/binding interface system designed to offer excellent grip when walking on icy or snowy paths. GW soles are made of two parts that can be mounted and replaced separately. |
