K-Frame Speed Rublo Clay

Created in collaboration with ATP player Andrey Rublev, the K-Frame Speed is K-Swiss' competition shoe for offensive players. The innovative K-Frame TPU locks the foot during aggressive lateral cuts and maintains stability during the explosive slides typical of clay, for sharp and agile movements. Hyper Foam guarantees energy return at every bounce, and the deep herringbone clay outsole delivers precise grip and slide control on clay. For offensive players who want ATP-level performance on the most technical surface.
