The Electra Sensor3 90 has a medium 100mm fit with a medium-stiff 90 flex index for expert all mountain women skiers. The Sensor fit liner is a true lasted liner to address the common problem fit areas. The seamless one piece tongue and cushy cutout instep pocket eliminate pressure points across the tops of the toes and that pesky instep bone. The women's Sensor3 has a special upper cuff that is not only lower but features a distinct "tulip" backward flare and scalloped profile to accommodate any woman's natural calf shape. The grippy rubber heel gives extra traction for walking around the resort. Strong all mountain women skiers can carve up the groomers and will appreciate the power and comfort of the Electra Sensor3 90.
