Mizuno Wave Rebellion Pro 3 vs Asics Metaspeed Ray:
Which to Choose

The single biggest difference is weight. The Metaspeed Ray is one of the lightest super shoes ever built at roughly 129g in a men's US 9, while the Wave Rebellion Pro 3 lands around 218g — a gap of nearly 90g that you feel on every turnover late in a marathon. That weight gap stems from how each shoe is constructed. The Ray strips everything back: a woven MATRYX upper and a three-quarter, forefoot-biased carbon plate that saves mass and leaves a touch of flex in the forefoot, riding on firm-yet-lively FF Leap (aliphatic TPU) foam that springs back sharply the instant you load it. The Mizuno takes the opposite approach to propulsion: a full-length carbon plate locked into bouncier Enerzy Lite+ superfoam, driven by its signature cut-off "smart heel" — an aggressively beveled, shortened heel that physically tips you onto your midfoot for a hard rolling, rockered stride. So the Ray feels feathery and eager with a quick, snappy bounce, while the Rebellion Pro 3 feels more forcefully propulsive and momentum-driven once it's rolling. The rest is close to a wash: drop is effectively the same (4mm vs 5mm), both are high-cushion but firm race platforms rather than plush, both are rated maximum for responsiveness, and both are genuinely tippy and unstable at easy paces — neutral shoes that demand solid form and punish slowing down. Both also share the super-shoe durability caveat: thin, pared-back race uppers that wear quickly and shouldn't be your daily miles, with the Ray's extreme minimalism sacrificing the most longevity of the two.
