Metaspeed Ray

The ASICS METASPEED Ray represents the pinnacle of featherlight racing innovation, engineered to give marathon athletes a near-effortless sensation of speed and forward drive. Incredibly lightweight — nearly disappearing on foot — this elite long-distance weapon is designed to make fast running feel fluid, sustainable, and explosive all at once.

The full-length FF LEAP superfoam midsole is ASICS’ bounciest, softest, and most responsive foam to date, delivering immediate acceleration and remarkable efficiency as the miles unfold. Combined with a lightweight carbon fiber plateand aggressive race geometry, the Ray maximizes propulsion and running economy, helping you maintain top-end speed deeper into the race.

Up top, the ultra-light Matryx upper provides airy security with targeted strength, ensuring a locked-in fit that never feels restrictive. Beneath, the ASICSGRIP outsole offers confident traction, translating every ounce of energy into forward force on race day.

Inspired by rei — Japanese for zero — the METASPEED Ray captures the essence of nearly weightless velocity, giving runners the sensation of pure, unrestrained flight from start to finish.
