In a rare and vibrant collaboration, KARHU joins forces with Rockets Cycling, Rotterdam retailer WOEI, and content collective Tour de Tietema (TDT) to reimagine the iconic Fusion 2.0 silhouette.
Tied to a shared love for performance, design, and colour, this special edition channels creative energy from cycling and sneaker subcultures into a bold, wear-anywhere runner.
The upper showcases a neutral silver-grey suede base accented by breathable beige mesh underlays, providing texture and ventilation in equal measure.
Splashes of brilliant blue around the collar and tongue offer dynamic contrast, while rainbow-striped lace loops inject a festival of colour, referencing both Rockets Cycling’s striking kit and TDT’s youthful, high-spirited identity.
These woven straps are functional, too, integrating seamlessly into the Fusion’s secure lacing system.
Additional visual storytelling appears across the tongue label, which features TDT’s signature logo atop a bright blue backdrop, and a vivid pink heel pull tab that adds a final flourish of flair.
The midsole is speckled with soft confetti tones, enhancing the celebratory feel of the entire design.
Despite the playful details, the silhouette remains grounded in functionality, with the Fusion 2.0’s recognisable layered panel construction built for durability, structure, and support.
Subtle reflective piping on the toe and heel adds visibility for low-light rides or evening city strolls, while the EVA midsole and grippy rubber outsole ensure this sneaker stays rooted in performance.
Finished with black KARHU branding on the lateral side and yellow Rockets Cycling script at the heel, the shoe brings together four brands in perfect harmony, each one contributing character, colour, and credibility.
