For decades, Kästle has been making high-end skis for everything from racing to Nordic and skimo. But what sparked their recent launch into the ski boot category? It’s far from a simple process, so Kara Williard talked with Alessandro Speranzoni, Kästle’s global ski boot product engineer, and Alex Pritzlaff, their U.S. product manager, to discuss the origins of the project; the design details of their boots, including their mysterious “Secret Mix” plastic composition; the 23/24 Kästle boot lineup; some new projects they have in the works, and more.
