Racetron is the skiboot made of Grilamid® designed for introducing young athletes to the world of international ski mountaineering competitions. It is the perfect alternative to race boots in composite materials, and uses Race-Ready solutions and technologies. The single lever, closure system with the exclusive, patented CavoBike mechanism Lever Pro, allows the transition from walk mode to ski in a single rapid movement, totally freeing the cuff thanks to this innovative solution. The top flap with triple adjustment and the lower Spider Ratchet with micrometric closure allow for maximum customization of the fit and the safe release of power during the descent. Compatible with TECH bindings, the boot uses the revolutionary, patented S4 Insert ™ front plate which facilitates boot to ski connection as never before. Thanks to the exceptional mobility granted by 75 ° inclination, the La Sportiva RaceGrip ™ sole and ISMF compatibility, Racetron is a fast, powerful, high performance boot for both uphill climbs and downhill skiing, and it is one of the lightest in its class. Racetron: for a new generation of champions.
