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.

Along with a vintage ski boot-inspired D-R Cinch lacing system and an asymmetric single-density EVA midsole, the Si-18 International Heritage provides unmatched comfort and support in a timelessly recognizable silhouette.
