First introduced in 1989, the K-Swiss Si-18 Premier is an iconic representation of K-Swiss’ dedication to honoring athletic heritage. Reengineered for extra comfort, the SI-18 International SDE combines a soft and Premium Suede upper, with a f ull-length EVA midsole. With its vintage ski boot-inspired D-R Cinch lacing system, the Si-18 International SDE is a timelessly recognizable silhouette.
