The Nordica Women's Pro Machine 105 Ski Boot is perfect for the intermediate to advanced skier. With a slightly softer flex than the 115, the Promachine 105 boot is perfect for the intermediate to advanced skier. It combines high-performance technology with a comfort-oriented women’s specific fit. By using softer liner materials and by articulating the rear cuff of the shell, thus providing more calf space, you are put in a more neutral stance, which decreases fatigue and preserves energy. For a high performance boot that women can use to seamlessly take their skiing from groomers to steep bump runs, the 105 is the perfect fit.
