Limited Edition ‘Supersonic’ Tech-1 KZ Karting Shoe. Featuring a distinctive red and black graphic inspired by cutting edge sportscar aero design, the striking Astars multi-layered logo appears to move around the outer surface of the Tech-1 KZ, perfectly encapsulating the sports performance of the shoe. The Alpinestars product design team incorporated the use of algorithm-driven design which repeated the logo on the surface of the shoe at an accelerated speed. This algorithmic design technique resulted in a unique imprint of the logo on the entire side of the Tech-1 KZ shoe, creating a unique moving action logo effect with a modern graffiti look.
Incorporating technical features proven in Formula 1 and specific innovations for the kart track, the new Tech-1 KZ Shoe has undergone a major evolution to continue to deliver outstanding performance in karting. New asymmetric instep lacing and Alpinestars’ exclusive wire filament closure system offers lightweight and precise support and anatomical forefoot profile, while new external reinforcements on the rounded heel and ankles provide high levels of protection and performance. Minimal stitching, a new compound ultra-thin F1 specification grip sole and new strategically positioned laser cut perforation zones make the Tech-1 KZ Shoe one of the most advanced shoes in karting.
