Inspired by the K-Swiss tennis archives of the 1980s, the Si-18 Rival is the brand's new shoe for Spring/Summer season. Featuring the Surgelite technology found in our performance tennis line, this lifestyle shoe provides superior comfort and cushioning to take you off the court. The design references the brand's origins and the Classic VN model with its five stripes. This hybrid sneaker embodies a "modern classic" style. It bounces between 80's heritage and performance tennis and condenses 60 years of history. Dive into the brand spirit while wearing the Si-18 Rival, a sneaker which can be worn on any court.
