The Mach 1 95 MV from Tecnica makes a great ski boot for powerful and aggressive skiers with a medium to narrow forefoot and medium to narrow shaft of the leg. Tecnica's CAS (Custom Adaptive Shape) Shell has an anatomical shape with dimples in common areas for skilled bootfitters to shape. Those dimples hold a punch very easily as well as creating a map for areas to stretch. The CAS Liner utilizes Microcell Material in the heel and ankle pockets that can be punched or heated for added customization and a performance oriented fit.
