K-Swiss Men’s K-Frame Rublo AC – Naval/Vintage

Co-designed with ATP star Andrey Rublev, the K-Frame Rublo AC is engineered for competitive players who demand speed, stability, and durability. With a bold Naval/Vintage colourway and a performance-driven build, this shoe is made to handle the rigors of high-intensity tennis on all court surfaces.

A TPU K-Frame structure enhances forefoot stability during explosive lateral movements, while the Hyper Foam midsole delivers lightweight cushioning and high energy return for quick transitions. The Duraprint upper combines breathability and support in a seamless, lightweight package.

To extend performance and longevity, DragGuard technology is integrated into high-wear zones at the toe and heel. The result is a shoe that feels fast, stable, and built to last through aggressive play.
