The Rossignol Speed 90 is designed for the solid intermediate skier who has a medium to wide forefoot and medium to wide calf volume. Rossignol's Sensor Matrix Construction uses a grid positioning structure on the upper cuff and lower shell to reduce the total weight of the shell and improve energy transmission to your skis. A softer plastic insert is molded across the top of the foot called the Easy Entry Insert. This allows your foot to slide in and out of the boot with little effort. Rossi's Optisensor Liner has an anatomically correct fit that has heat moldable properties in the forefoot with more rigid padding in the heel and ankle pocket to keep your heels locked into place. If you want a wide fit and a sturdy performance, the Rossignol Speed 90 is a great option for you.
