First introduced in 1989, the Si-18 International is an iconic representation of K-Swiss’ dedication to honoring athletic heritage while optimizing performance for future design. 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 ground breaking Silicone Formula 18 for which the shoe is named. 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. The collaboration with Stadium brings back the Si-18 Premier as if it was vintage. The slightly off-white color gives the appeal as if it has been sitting in a closet for decades. The colorway nods to Stadium’s own company colors while still looking like it was an actual retro color from the catalogs. Stadium respects the iconic look of the original Si-18 and really wanted to reimagine their own brand colors in the same heritage way.
