One of the biggest challenges with any ski boot is finding one that fits well, and still performs like you want it to. This can be an even bigger challenge for women who generally have a different foot and leg structure than men. The Rossignol Electra Sensor3 90 is a great intermediate to advanced boot for women. It is specifically designed with F.I.T.(Feminine Intuitive Technology). This means that the Rossignol Electra Sensor3 90 has a female tailored cuff, narrow heels, and narrow forefoot shape. With the Rossignol Sensor3 technology the heel and metatarsals are in contact with the shell to increase power and response, but the 100mm last offers plenty of space for a medium width foot. Heel hold does feel pretty good, but this isn’t a super tight race boot. The liner is quite comfortable out of the box, but may need a bit of customization to fit perfectly. It does contain Thinsulate insulation to help keep the foot warm, and the one piece toe box helps to increase comfort by reducing pressure points. With a flex of 90, it is stiff enough for aggressive skiers, especially if you are light-weight. Heavy aggressive skiers may find the flex to be a bit soft. The Rossignol Electra Sensor3 90 does have a mild 14 degree forward lean. This is pretty neutral and while it helps with balance, control, and fatigue, aggressive skiers may long for a bit more significant angle. Overall, the Rossignol Electra Sensor3 90 is a good option for intermediate, advanced, and light-weight expert skiers who are looking for a high performance boot, which is still comfortable. It has women specific features designed to accommodate the calf and foot structure of a women to increase comfort and performance for women skiers. Heavier skiers may find the flex to be a little soft, but really only advances or expert skiers will want more.
