ASICS Gel-Kinetic Fluent SHUSHU/TONG Black White — Ballet and running in the same sneaker
SHUSHU/TONG is the Chinese label founded by Liushu Lei and Yutong Jiang, known for its exaggerated femininity and bows. Its collaboration with ASICS, presented during Paris Fashion Week in June 2025 and launched from August that year, starts from a clear idea: reinterpreting archival running silhouettes through the language of ballet. The GEL-KINETIC FLUENT is the chosen base, and this black-and-white version is the most graphic in the series.
The GEL-KINETIC FLUENT — Archival runner with a bow
Built on the running silhouette, with its technical mesh and structured overlays, the collaboration adds SHUSHU/TONG’s signature detail: the bow on the upper, which completely transforms the way the sneaker is perceived. The black-and-white contrast emphasizes the lines of the upper and makes each panel clearly stand out.
Materials and technology
- Upper: Technical mesh with white and black synthetic overlays and SHUSHU/TONG’s signature bow detail
- Interior: Padded lining, thin tongue, and removable cushioned insole
- Sole: Midsole with ASICS GEL cushioning and a rubber outsole with traction for everyday use
