ASICS UB9-S Gel-Kayano 20 'Kiko Kostadinov Vibrant Yellow' (2024)

Kiko Kostadinov x ASICS UB9‑S Gel‑Kayano 20 'Vibrant Yellow' fuses cutting‑edge design with heritage performance in a collaboration between ASICS and acclaimed designer Kiko Kostadinov. Part of the UB9‑S Gel‑Kayano 20 series that debuted in October 2024, this vibrant reinterpretation elevates the classic Gel‑Kayano 20 silhouette—originally introduced in 2013 for its pioneering GEL cushioning technology—into a contemporary sportstyle icon. Kostadinov’s influence brings asymmetrical pull tabs, layered mesh, and bold color storytelling to the forefront, seamlessly bridging functional footwear engineering with avant‑garde fashion sensibilities.

Overview

Rendered in an eye‑catching Vibrant Yellow/Pure Silver palette, this UB9‑S Gel‑Kayano 20 iteration stands out with its breathable open‑cell mesh upper wrapped in striking yellow that enhances ventilation and everyday comfort. Structural support comes from synthetic overlays and a FLUIDFIT cage that secures the foot while maintaining a sleek, modern profile. The midsole houses ASICS’ signature full‑length GEL technology to deliver responsive impact absorption and plush comfort underfoot, making it ideal for all‑day wear. Additional design touches include metallic silver accents and tonal details that reinforce the collaboration’s refined yet bold aesthetic language. Released on October 24–25, 2024, the Vibrant Yellow colorway continues to blur the line between high‑performance running shoe heritage and contemporary streetwear appeal.
