Rossignol Alltrack 90 Ski Boots Black Red Grey

The Rossignol Alltrack 90 is a boot that does not give up anything and is designed for skiing all over the mountains. The detachable leg cuff offers a natural range of motion for hiking and the 102 mm last ensures a comfortable fit. The outer shell with Generative Design Grid is designed to minimize weight and total power transmission on track, off track and anywhere in between. The custom-made booty provides greater comfort.

Features:
- Easier to ski, better fit Dual Core technology provides specific power transmission and the outer shell wrap for greater responsiveness in rebound, response and control
- Lightweight, full power, Generative Design Grid technology minimizes boot side thickness and maximizes efficient use of material to reduce weight and improve energy transfer
- Optimized hiking mode, the lower boot shell is designed to offer a 50 degree range of motion when walking for effective touring and maximum skiing power
- Gripwalk compatible design (not included). Gripwalk soles feature a rubber band and curved toe for natural movement and increased traction
- Regular Fit, this regular cut version has a 102 mm last that provides a comfortable and anatomical feel regardless of the shape of the foot

Technology:
- Generative Design Grid:
A new progressive approach to data-based design that harnesses the power of generative design software to create the ideal boot shape. The Generative Design Grid outer shell design, focused on minimizing wall thickness to reduce weight while improving power and support, offers the best combination of both features.

- Custom T4:
The customised boots offer personalisation on the inner padding to better wrap the foot and provide more comfort. The T4 version has mono injected polyethylene padding for constant soft density in the performance and fit zones.

- Dual Core Technology:
The 'power injection' method allows two different plastic durometers to be injected at the same time. This unique single injection process allows for specific power transmission and outer shell wrapping. In addition, it creates the Dual Core sandwich construction throughout the housing, resulting in more vivid bounce, responsiveness and total control throughout the turn.



- Hike Mode 2.0:
The new optimized hike mode includes a wider opening at the back of the lower housing and a lower rotation axis to optimize range of motion and upward mobility (50 degree ROM). The articulated bottom insert and metal-on-metal locking mechanism increase rear support while providing maximum downward power transmission.
