ALPINESTARS TECH-1 KX V3 SHOES BLACK ORANGE
Kart racers looking for a shoe that disappears on the pedals will find it in the Alpinestars Tech-1 KX V3 Shoes Black Orange Fluo, a first-generation FIA-homologated design built around minimal weight and maximum feedback.
Every panel is thermo-welded into a single seamless shell made from ultra-thin polyurethane film, removing the seams and pressure points found on older-style racing shoes. Laser-cut vents run along the toe and both sides of the upper, and a 3D mesh tongue adds a second layer of airflow, keeping the foot cool through long stints. The overall shape borrows from Formula 1 footwear development, resulting in a revised asymmetric lacing pattern that wraps more tightly and evenly around the foot than previous versions.
Support comes from a two-part closure: an adjustable strap and a speed-lace system built with aramid fiber, secured by Alpinestars’ own wire-lock hardware for a fit that won’t shift mid-lap. Underneath, a thin rubber outsole with a textured tread pattern is designed for maximum pedal sensitivity while maintaining grip in hard braking zones. External reinforcement protects the heel and ankle, and internal padding guards the toe against abrasion. A lower-cut microfiber collar frees up Achilles tendon movement, while a lightweight one-piece heel-and-insole construction keeps the foot locked down and comfortable for the full duration of a race weekend.
