Rossignol ALLSPEED 80 are comfortable and adjustable ski boots with aerodynamic construction intended for advanced skiers. Medium width of 102 mm offers comfort through anatomic shape. OptiSensor liner adds to the comfort, insulation and foot support. Top quality monoinjected construction with several flex and canting settings ensures optimal fit and performance tailored to every skier’s needs, posture, and foot shape. The new aerodynamic Sensor Blade technology at the shell decreases the amount of material used, reducing weight and ensures an incredibly effective transfer of power directly into the skis.
