There really isn't much that the Tecnica Mach1 MV 130 Ski Boot doesn't offer, be it all-mountain performance, stiff response, or a perfect fit. This mid-volume version of Tecnica's high-performance Mach1 line is also among the stiffest, featuring a responsive flex for aggressive or heavier skiers. A carbon insert in the rear spine of the cuff further increases power transfer between you and your skis. The mid-volume last fits most average feet, or offers a performance fit for wider-footed folks. Fully thermomoldable to get things just right, the Mach1's CAS construction nonetheless comes anatomically shaped for comfort right out of the box. If you want it precisely dialed to your fit, though, you can punch out the shell or heat the liner up to get it feeling just right.
