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. When you add the Asymmetrical Power Transmission shell and cuff design in a 115 flex to the equation you get a precise and powerful boot that is completely at home charging down any type of terrain or snow condition the mountain can throw at you. The Mach1 MV 115 W is the go-to boot for the ladies who want to shred the whole mountain at the highest level. Women2Women approved!
