  • K-Swiss celebrates its performance tennis heritage with the reissue of the Si-Defier 7.0. Originally worn exclusively by the championship doubles team at the 2000 French Open, the Si-Defier was part of the innovative 7.0 system, featuring advanced technology and innovative design. Details include 7.0 system badging, a leather upper, and unique molded 5 stripes. This is a nostalgic piece of history, brought out from the archives to highlight our passion for tennis innovation and to showcase authentic bold and chunky sole statements.
