K-Swiss brings back their signature Si-18 International OG model this holiday season. Originally introduced in 1989, the reissued tennis shoe is built with the same craftsmanship as the original, including: K-Swiss’ exclusive Si-18 cushioning, technical D-R-Cinch lacing system, and heel stability counter to enhance on-court performance. The model’s premium white leather build is complimented with flag emblems representing each Grand Slam tennis tournament host country.

The Si-18 International OG is now available in limited quantities online and select stockists.
