S4+ Yogiri

Yes — give the people what they want! The ASICS S4+ Yogiri brings super-shoe innovation to the strong, proud, everyday runner, combining premium racing tech with a stabilized design that makes the marathon distance feel smoother and more attainable. Say it with us: S4+ Yogiri — built around the four S’s of speed, stability, safety, and sub-4. With its balanced geometry and guided efficiency, this racer is specifically crafted for runners targeting a sub–4-hour marathon, offering race-day performance without the hyper-aggressive demands of elite-only models.

The dual-layer midsole features ASICS’ most advanced FF TURBO+ superfoam on top — the same explosive material used in the METASPEED Paris line — delivering lively rebound and race-ready responsiveness. Beneath it sits a layer of FLYTEFOAM cushioning that enhances stability and comfort, helping maintain form when late-race fatigue sets in. A full-length carbon plate adds energetic propulsion, while the widened contact platform provides steady guidance and confidence through all 26.2 miles.

With a softer, more forgiving engineered mesh upper, the Yogiri prioritizes comfort for normal runners who may spend significantly longer in their racing shoes. Rounding out the package, a full-length ASICSGRIP outsole supplies excellent traction and durability, ensuring secure footing from the starting cannon to the final finishing surge.

For runners craving a marathon super shoe built to support you — not just the elites — the ASICS S4+ Yogiri delivers the perfect balance of speed and stability for chasing down meaningful PRs with confidence and joy.

MIDSOLE

• FLYTEFOAM bottom layer is lighter than other EVA foams, for a lightweight, comfortable, and steadied experience.
• Full-length carbon fiber plate adds snappy rigidity for toe-off propulsion, but its expanded contact area creates greater inherent stability.

OUTSOLE

• ASICSGRIP provides full-length grippy traction for confidence and cornering on variable road conditions.

UPPER

• Engineered mesh is designed to be softer and more comfortable than other racing uppers, while maintaining breathability and low weight.
