Details

This collaboration with Chicago native Leaders 1354 looks to the city flag as the center of inspiration for this launch. Details referencing the light blue stripes and red stars are executed through the upper and outsole.

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 groundbreaking Silicone Formula 18 for which the shoe is named. Leaders 1354 stars accents adorn the heel with the tongue displaying the Leaders 1354 emblem. Along with 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.

Original PU midsole construction
Light-weight rubber outsole with the design DNA of the original shoe.
Signature D-R Cinch lacing system and heel stability counter for optimal support in lateral movement
TPU shank on the midfoot for stability and support
Premium leather upper
Micro-perforation toe box
Poplin and TPU stripes
