The Kiara Sensor 50 has a wide 104mm fit with a introductory 50 flex index which is ideal for begginer 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 Sensor 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. In the Kiara Sensor 50 women will stay warm and comfortable all day long.
