The Mach 1 LV 130 TD is the benchmark for performance, fit and customization in the high-performance low volume ski boot world. Grounded in the fundamentals of high-performance ski boot design, the LV 130 features T-Drive technology which is a revolutionary carbon fiber shell to cuff connection that allows the boot to function in a much more efficient way, resulting in a smoother more consistent flex, better performance and less energy required to ski at a high level. When you add the Asymmetrical Power Transmission shell and cuff design 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. Fit is priority number one in the LV 130 and Custom Adaptive Shape C.A.S. technology is the way we achieve it. Developed with alow volume anatomically shaped shell and liner, the C.A.S. technology provides a great fit right out of the box but allows the boots to be fully customized if need be. The Mach 1 LV 130 TD is the go-to boot for the highest level, all-mountain chargers.
