The Fast-R Nitro Elite 3 looks like it was designed by removing everything that wasn't strictly necessary. A carbon PWRPLATE runs through a partly decoupled Nitrofoam Elite midsole, and a large cutout underfoot saves weight and leaves the plate on show. The ride is lively and aggressive, almost pitching you forward at pace.
It suits fast, efficient runners racing anything from 10K to the marathon, particularly those who stay on the midfoot. At easy paces it can feel awkward and unsupported, so keep it for the days that count.
It is more radical than the Rocket X 3 or Hyperion Elite 4, and closer in spirit to the Metaspeed Sky Tokyo: light, fast and demanding. At $300 it also shares the top price on the shelf with the Cloudboom Strike. The fit is snug and race-specific, with a thin upper that wraps the foot closely.
“Wild-looking, frighteningly quick, and not for slow days.”

ZoomX LT foam, a wider Flyplate and quieter Air pods, about 10 grams lighter than before.
Air pods, ZoomX and a full carbon plate, now light enough to stop apologising for.
Energy rods instead of a plate, and a rocker that rewards a forefoot strike.
