Size Guide

  • The Si-2018 Fusion L carries on the storied Si-18 International lineage, showcasing forward-thinking, court-inspired style in a bold sneaker design. This low-top active sneaker features a leather and mesh upper with a slip-in, bootie-entry for a close and secure fit. Its classic-style leather vamp is perforated for venting while its leather heel counter features an oversized 3D printed K-Swiss wordmark for a bold, modern look. A medial side 5 stripes detail in elastic webbing contributes to form and function, crossing over the tongue and under the lace-up to add stretch, stability and support. K-Swiss’ signature Aösta 7.0 high-density rubber is used to create the Si-2018 Fusion L’s reinforced toe bumper and durable outsole with deep herringbone tread, for a unique sneaker that bridges tennis-specific technology with street style looks.
