The ultra-warm and cozy Rossignol Women's Electra Sensor3 90 Ski Boot features a Sensor Fit pressure-free liner, efficient and powerful Sensor3 shell, and Thinsulate insulation. A women's-specific cut accommodates a wider lower calf, narrow heel, and smaller forefoot for a true performance fit. Larger aluminum buckles give you more torque for easier adjustments and an uncompromising fit. Slip your foot into this boot's notched instep with ease, and get into its neutral stance for optimal power and control and less fatigue. A 90 flex index lets you charge down the mountainside with liberating aggression, and a 100-millimeter last allows room for forgiving, all-day comfort while you bomb downhill. Like a lady, of course.  

Rossignol's Sensor3 line of boots is ideal for expert to advanced skiers looking for powerful all-mountain performance and the precise fit that a 100mm last offers. The Electra 90 is the stiffer of the two women-specific boots in the series.
