Si-2018 Fusion L | K-Swiss US

STYLE NEVER SIDELINED

We welcome the newest addition to the SI-18 family, the Si-2018 Fusion Leather.

This refreshing update to a 1989 classic is the only pair of shoes that truly unites tennis roots with street-wear to create that unique look.

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.
