An unapologetic, hyper-aggressive marathon super shoe built for maximum mechanical return. Packing 39.5mm of ultra-springy PWRRUN HG foam and a slotted carbon plate into a 204g chassis, its aggressive Speedroll rocker violently snaps your foot through the toe-off phase at race pace.

Verdict: buySkip it if
You want a roomy toe box for long racing or wide feet. Doctors of Running fit logs describe the forefoot pushing on toes; 74% of sources call the toe box narrow.
You want a stable platform at easy and walking paces. The aggressive late-stage rocker plus 39.5mm stack wobbles the moment stride tempo drops.
You do training mileage rather than racing. The $275 race-weight build shows midsole fatigue early; training rotations eat it fast.
You expect an intuitive first run at any effort. The slotted plate needs pace to come alive: slow-pace testers file the ride as distant and unstable.
