The Rossignol Speed 120 Ski Boots are solid expert level boots that happen to fit a very wide and high volume foot extremely well. Sensor Matrix reinforcing gives additional beef to the solid polyurethane shell and cuff, and the excellent Optisensor T2 liner is insulated with Thinsulate™ Platinum fibers for extra comfort on colder days. The days of having to settle for a sloppy 2 buckle "comfort" boot are over; get with the Rossi Speed 120 and enjoy a real boot that's actually comfortable and fits your foot.
