The Rossignol Alias Sensor Ski Boots have everything you need and nothing you don't. By combining the asymmetrical toe box, versatile-fitting instep and more articulate ankle area, the Alias Sensor 100 delivers a comfortable, forgiving fit without sacrificing powerful, all-mountain performance. The Sensor Shell uses a boot board that connects the three key receptor points to the boot sole to produce enhanced power, control, and feel.
Sensor Fit All Sensor constructions have a common modern toe box, accommodating instep, and strong heel cup. The generous toe box is asymmetrically shaped to fit normal foot shapes for ultimate comfort and warmth. The instep is extremely versatile, fitting many different instep heights, providing an accurate wrapping.
104 mm Last In Sensor boots, the bootboard is reinforced in the forefoot to allow 2 points of contact with the Sensor insert. The insert is made of more flexible material to make it more forgiving and more comfortable. The 104 mm internal last offers both support and superb comfort.
Sport Thermo Fit Plus Every liner is designed for a particular internal last and boot construction. It is shaped to be a perfect match with the inside of the shell, which is especially important in terms of the length of liner in the toe box and heel retention for a precision liner that is comfortable from the moment you put it on.
One-Piece Toe Box One piece construction keeps the toe box in shape, so there are no painful deformations when you put the boot on. There are no seams on the front of the tongue, and the instep is very shaped and padded. This eliminates pressure points over the toes and instep.
