Rossignol AllTrack 80 W Ski Boots - Women's 2017

Flex: 80: A medium flex for a combination of comfort and high-performance support.

Thermo Optisensor 3D T3 Liner: OptiSensor 3D liners deliver a new level of optimized foot wrapping, comfort and support. Strategically placed materials in three-key fit zones maximize the interaction between the foot, liner, and shell. Softer ankle and instep areas increase comfort and foot wrapping. A stiffer heel cup provides superior heel lock, increasing support and control for enhanced performance. New Thinsulate™ lining increases warmth for all-day comfort. Impressive "out-of-the-box" fit with unparalleled performance.

Women's Liner: Women's liners are cut lower to accommodate differences in calf shape. They also have a more open design for a more comfortable fit. The padding in the upper liner is very flexible to prevent any discomfort around the calf.

Thinsulate™ Insulation: Targeted in the forefoot.

Shell: Polyether

Cuff: Polyolefin

Bootboard: Polyurethane

Sensor Grid: Diagonal grid positioning improves shell wrapping while also reducing weight and increasing torsional rigidity. Resulting in enhanced power, precision and energy transmission.

Forward Lean Angle: 12.4°

Posi-Block Technology: In ski mode, reinforced vertical ribs in the upper cuff lock upper and lower shells together, delivering unprecedented downhill performance. In hike mode, the lower shell's U-shaped profile in the rear allows maximum range-of-motion for comfortable hiking and walking.

Diagonal Buckles: Patented diagonally-oriented buckles provide better shell wrap and fit, and are easier to align during entry and exit. The diagonal angle pulls the foot back into the heel pocket for increased support.
