The Mach1 MV 115 W is the benchmark for performance, fit and customization in women’s high-performance ski boots. Fit is priority number one and an anatomically shaped 100mm medium volume shell and a women's specific liner with Custom Adaptive Shape - C.A.S. - technology, provides a great fit right out of the box but allows the boots to be fully customized if need be. T-Drive technology, a revolutionary carbon fiber shell-to-cuff connection, allows the boot to function more efficiently, resulting in a smooth, consistent flex and better performance while using less energy to ski at a high level.
