The Dalbello Men's Panterra 100 Ski Boot is an extremely comfortable all-mountain boot built with a unique three-piece construction for a better performance on groomers, powder runs, and everything in between. This three-piece construction, code-named Cabrio, provides a smoother, more progressive power transmission as well as excellent shock absorption, dynamic rebound, and a more consistent 100 flex compared to boots with a standard two-piece construction. In addition to the three-piece design, Dalbello's Contour 4 shell fit features pre-punched areas designed to comfortably accommodate navicular, metatarsal, and ankle bones, and an IF Performer liner that's specially formed to fit the Panterra's shell shape. It's also heat moldable, and the shell comes with an adjustable heel inclinator, canting mechanism, and flex, so you can dial it in to your exact specs.
