Designed with input from Tecnica's Women2Women program, the Mach 1 LV 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.
