Designed with input from our Women2Women program, the Mach 1 105 W with T-Drive Technology is a high-performance ski boot specifically designed for strong female skiers who need just a touch more forgiveness than the 115 offers. Fit is priority number one and an anatomically shaped 98mm low 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 shell-to-cuff connection, allows the boot to function more efficiently, resulting in a smooth, consistent flex and better performance while using less energy for all day performance. The Asymmetric shell and cuff design in combination with the Women's Natural Stance set-up puts you in the perfect balanced position to tap into the power and support you need to charge all over the mountain with control and confidence. Get out there and shred ladies.
