WOMENS SI-18 INTERNATIONAL HERITAGE

WHITE/CLASSIC BLUE/RIBBON RED

Size Guide
  • First introduced in 1989, the Si-18 International is an iconic representation of K-Swiss’ forward-thinking, performance shoe design. Built around technical function specifically for tennis, this classic reissue carries many of the same legendary features, including its signature D-R-Cinch lacing system and heel stability counter designed for enhanced performance on the court. The mid top sneaker’s full leather upper is complemented by vintage branding elements, including an embroidered tongue tag that pays homage to the four host countries of tennis’ most prestigious tournaments.
