The Rossignol Alias Sensor 90 is a great ski boot for bigger intermediates that have a wide forefoot and wide calf volume. Rossignol has developed a more neutral stance that is more upright for more efficient turning, especially on modern skis with rocker. The Sensor Liner has a snug and contoured fit. The 104mm last is great for skiers who have had problems finding a boot with an adequate flex with a wider fit in the forefoot. If you have a wider foot and are looking for a ski boot that will keep you comfortable, but give you the stability that you need, the Rossignol Alias Sensor 90 will be a great choice.
