Rossignol Vita Sensor 2 70 Boot: 

The Vita Sensor2 70 has a medium wide 102mm fit with a moderate 70 flex index for advanced all mountain women skiers. In the Vita Sensor2 70 women can ski in any condition feeling cozy and warm in their ski boots all day long.
SENSOR 2 performance / tolerance, 2 points of contact - in the front, reinforced bootboard. Bootboard in direct contact with: Rigid Sensor2 insert. The Sensor 2 shell uses a bootboard that focuses on connecting the 2 key receptor points to the sole of the shell (forefront area). The direct link with the reactive hard insert produces power, control and feel. 102 mm last is the right cross between comfort and performance.

DEDICATED BUCKLES
The large diagonal buckles on Kiara orient the bails and catches in a diagonal direction, providing a better shell wrap and fit. The diagonal angle pulls the foot backwards into the heel pocket. The buckle lever is larger for easier opening and closing with mittens on.

DEDICATED EASY OPEN CUFF (Patented)
A cuff that's very easy to open and close thanks to a hinge made of highly supple material.

DEDICATED WOMEN CUFF
All products for women have female-specific cuffs. The cuff height is significantly lower. The tulip-shaped rear section easily accommodates a woman's natural calf shape. The 2 cuff buckles are set lower for easy closure and better foot wrap.

DEDICATED WOMEN LINERS
All shells for women have liners specifically designed to suit the female form. Women's liners are cut lower to accommodate the female calf shape. They also have a more open shape for a more comfortable fit. The padding in the upper liner is very flexible to prevent any discomfort around the calf. The lining fabrics are very soft and comfortable. A soft cozy women foot bed with heel lift for women's specific balance (Electra_Vita).

NATURAL WOOL
Natural wool placed around the toes for warmth and comfort.

ONE PIECE TOEBOX
The solid one piece toe box is integrated into the toe box construction to prevent deformation when entering for an initial "wow" factor. The seamless one piece tongue and cushy cutout instep pocket eliminate pressure points across the tops of the toes and that pesky instep bone.
