Asics MetaSpeed™ RAY Tokyo White

Built for: Racing — and almost nothing else.

The METASPEED RAY is the lightest racing shoe ASICS has ever produced: 129 g on the lab scale, which is barely more than a track spike. FF LEAP aliphatic TPU foam sits under a three-quarter-length carbon plate that deliberately leaves flexibility in the forefoot, and lab-measured energy return hit 81% at the forefoot and 78% at the heel — among the highest figures ever recorded.

Why it works

• 129 g — one of the lightest running shoes ever built, in the class reviewers now call "hypershoes".
• FF LEAP aliphatic TPU midsole: 81% forefoot / 78% heel energy return in lab testing.
• Three-quarter-length carbon plate that keeps some forefoot flex rather than locking it out.
• MATRYX upper — the abrasion-resistant woven material used on technical racing footwear — over a 0.9 mm ASICSGRIP outsole.

Race-day details

• Surface: Road, race courses
• Best for: Racing, best suited to forefoot and midfoot strikers; many reviewers recommend 10K and shorter for most runners
• Drop: 5 mm (ASICS stated) — 39.8 mm heel / 30.0 mm forefoot, lab measured
• Weight: ~4.6 oz / 129 g (men's US 9)
• Ride: Extremely light and springy, on a very narrow, unstable platform — this is a specialist tool
• Note: The 0.9 mm outsole means minimal durability. Save it for races.
