As a lesson in comfortability and functionality, the Women's Mach1 MV 105 W Ski Boots don't skimp on the high-performance, ultra-comfort technology that puts them at the top of any advanced - expert women skier's wishlist. With a construct designed for medium-volume feet, the shell remains customizable with Tecnica's Custom Adaptive Shape that uses thermoforming to accurately mold to your foot's unique shape. Using the C.A.S. System in the liner and tongue, you get the most accurate fit right out of the box so you can start shredding as soon as possible. When you're carving and hitting sharp turns on-piste, T-Drive technology adds precision and power to your edge-to-edge drive by connecting the cuff and shell, reinforcing the boot's flex to provide power all around the mountain.
