The Women"s Sensor Shell has been 100% designed with F.I.T. (Feminine Intuitive Technology), which addresses women"s unique fit issues that include narrower heels, smaller forefoot shapes, and lower cuffs to accommodate a lower, fuller calf. The Rossignol Kiara Sensor 50 is perfect for beginner to intermediate women looking for a great recreational boot. To help keep your toes warm and toasty Rossignol offers you a quilted goose down toe box to improve the overall warmth of the liner. Oversize buckles that are easier for a smaller or gloved hand to close with tension when you have gotten the rest of the family dressed and out the door and you are the last one to be ready. A tulip cuff is lower and has a backward flare to accommodate a women"s calf shape. Notches in the plastic at the instep area make getting in and out of boots a cinch (a long standing problem with women"s boots).
