Metaspeed Ray

Ultra-light, all-out race shoe using a full slab of FF Leap (ATPU) foam and a forefoot–midfoot “teardrop” plate. It sits above Sky/Edge Tokyo on price and weight savings, trading stability and durability for pop and fewer grams.

Exceptionally soft, springy and lively with a quick, late rocker. More “bounce” than “snap.” Feels electric at fast paces but gets wobbly, especially at the heel and in tight corners. Less forgiving at easy pace.

True to size for most. Race-fit with a snug/narrow midfoot and airy toe box; minimal padding; skinny tongue/laces can fuss during lockdown. Heel collar is very stripped-back; mild heel slip reported by some reviewers.

• Astonishingly light for a carbon-plated marathon racer
• Big, energetic rebound that makes hard paces feel easier
• Comfortable forefoot cushioning for long fast efforts
• Breathable, disappear-on-foot upper

• Noticeably unstable (more so at the rearfoot)
• Minimal outsole + exposed foam = questionable durability
• Fussy lockdown; narrow through midfoot for some
• Intended for fast, forefoot running--all others need not apply
