Guaranteed Safe Checkout

Designed using F1-tested technology; the new Alpinestars Tech-1 KZ Shoe has further evolved to provide drivers with top karting footwear. The latest asymmetrical instep lacing system coupled with strategically placed perforated ventilation zones along with the sleek anatomical profile of the design provides unsurpassed levels of comfort, fit, and performance, while external heel, ankle, and internal toe reinforcements aid protection and durability while reducing abrasion. Breathability and weight-saving are further enhanced through the minimal use of stitching and the incorporation of the latest materials such as PU film and 3D mesh on the tongue. Driver comfort and feel are optimised through the use of soft padding on the tongue and collar, a lower cut on the rear for greater Achilles flexibility, and using Formula 1 derived technology, the Tech-1 KZ uses an exclusive, ultra-thin rubber compound in the sole for greater driver feel, grip and sensitivity in all conditions.
