K-Swiss has made noise this year thanks to enlisting relevant celebs like Diplo to help push their latest and greatest. That doesn’t mean that the once profound athletic purveyor isn’t above referencing its storied past, as the brand’s own tennis classic, the K-Swiss SI-18 International, is back. Referencing a number of tennis majors, this ‘Wimbledon’ inspired two shoe duo is available right now. With an ominous black upper on both releases, one even sports country flags stitched onto the tongue and heel in reference of the hosting destinations for tennis’ most prestigious events. You can pick up your pair today directly from K-Swiss.
