The TECH-1 KX V3 Shoe has an advanced, seamless thermo-welded construction consisting of ultra-thin PU film and textile to provide supremely lightweight performance and excellent comfort and fit. Laser cut air-intakes and perforations on toe and both sides for added breathability. First shoes homologated to new FIA karting standard. Bringing Formula 1-derived features, along with specific innovations for the kart track, the new Tech-1 KX V3 Shoe is now lighter and more breathable with a revised asymmetric lacing system to conform more closely to the foot. The use of thin PU film adds durability whilst reducing seam construction and pressure points. Laser cut-outs and perforations in the film, combined with 3D mesh, offer maximum breathability.
