Asics Gel-Kayano 12.1 Running Sneaker 1203A976-001

Asics Gel-Kayano 12.1 — Heritage Running Remastered

The Asics Gel-Kayano 12.1 is a love letter to one of running's most storied silhouettes — reengineered for the way we move today. Drawing directly from the Gel-Kayano 12's original architecture, the 12.1 retains the structured support and cushioned ride that made the franchise legendary, while updating the materials and proportions for a lifestyle-forward aesthetic that works as well off the track as on it. This is performance heritage, worn daily.

Design Heritage

The Gel-Kayano lineage began in 1993 and has since become one of the most trusted names in stability running. The 12.1 revisits the silhouette of the 12th generation — a pivotal chapter in the franchise — and translates its DNA into a contemporary runner that honors the original without being bound by it. The result is a shoe that carries decades of biomechanical research in every step.
