There's no point in beating around the bush: the Tecnica Mach1 130 LV Men's Ski Boot is a hard charging, take no prisoners, race bred freeride boot that's not particularly interested in slowing down, taking it easy, or just cruising. In addition to a burly 130 flex, well defined heel pockets, taller cuffs, and pre punched navicular areas, the Mach1 boasts the same 98mm last and easy onoff Quick Instep Max overlap construction featured on Tecnica's World Cup conquering Inferno boots. This construction is key, since it makes the Mach1 perfect for lower volume feet hence the LV or even more precise for skiers who are looking for the ultimate performance fit. The sculpted polyether shell provides a snugly confident fit around the foot, while the stiff polyester cuff gives the power to conquer big lines and big drops at high speed without worrying about feeling loose, soft, or wobbly in your boots. Tecnica designed the Custom Adaptive Shape C. A. S. UltraFit Pro Race liner to exactly match the contours of the shell, giving you a seriously precise and powerful out of the box fit that won't pack out after half a season like traditional liners tend to do. The LV uses a thinner and more responsive liner than the classic Mach1 for more sensitivity and less chance that it will pack out and get sloppy. The C. A. S. liner is also designed to be heat molded for a fine tuned fit, giving you the ability to rip in comfort from the first chair to the last run. A fat 45mm power strap lets you cinch everything down for snug and powerful feel, and the Mach1's subtle canting and flex adjustments give you the ability to dial your stance. When the TechniGrip soles wear out, you can replace them for more grip and surer binding release and retention, or you can swap them out for a full length pre canted sole to address any alignment problems you're having. If you like to push your skiing and need a boot that can keep up, the Mach1 130 LV is a pretty damn good bet.
