This reissue of the award-winning style combines elements of classic K-Swiss tennis, such as a premium leather upper, with innovative engineering that introduced the world to the groundbreaking Silicone Formula 18 for which the shoe is named. Along with a vintage ski boot-inspired D-R Cinch lacing system and an asymmetric single-density PU midsole, the Si-18 International Heritage provides unmatched comfort and support in a timelessly recognizable silhouette.
