Asics MetaSpeed™ SKY Tokyo Red

First, red is the universal color of racing intent. The Asics MetaSpeed™ SKY Tokyo Red pairs that urgency with Asics' stride-length optimization platform — FF TURBO PLUS foam and carbon geometry designed to make longer strides more efficient. For runners who go to the start line already decided.

Moreover, the MetaSpeed Sky Tokyo was developed with Tokyo Marathon course data — flat, fast, and demanding consistent propulsion efficiency across 42.195 km of urban road.

FF TURBO PLUS (PEBA) + Stride-Length Carbon Geometry: Built for Tokyo

Additionally, fF TURBO PLUS PEBA foam delivers race-quality energy return on a platform calibrated for stride-length runners. The carbon plate geometry of the MetaSpeed Sky Tokyo is designed to extend stride length at race pace — storing energy at mid-stance and releasing it at toe-off in a way that rewards runners whose natural acceleration mechanism is stride extension.

Race mesh upper: featherlight adaptive fit. ASICSGRIP rubber outsole. 171 g. 5 mm drop. 39.5 mm heel stack. Stride-length optimization for marathon and half-marathon racing.

For Who?

For stride-length runners targeting marathon and half-marathon times. Best for mid-foot to heel strikers who get faster by extending their stride.
