The Cielo X1 3.0 is a top-tier race shoe with a wild, squishy, and explosive ride that edges out the Fast R3 on bounce and cushioning; both reviewers would reach for it for races up to the half marathon.
Best for: 5K to half marathon racing for runners who want a bouncy, propulsive ride with good road protection
+5 earlier reviews from The Run Testers
Got a half marathon PB in them — pretty fantastic, really bouncy, perfect on a slightly hilly course. Still wonders if Rocket X3 might suit him better for the marathon distance.
Best for: Half marathon racing on rolling courses with downhills; bouncy enough to give a midfoot/forefoot-style boost even to a shuffly heel-striker.
Mike rates it 4.5/5 for 10K race testing — fast, lively, more stable, hard to fault. Built on v2 in the right ways without losing punch.
Best for: 10K racing in wet conditions — punchy and aggressive but more controlled than v2.
All three testers call it Hoka's best carbon racer to date — lighter, bouncier, more stable than v2, and accessible to a wider range of runners while keeping the punchy aggressive personality. Mark prefers Asics Metaspeed Sky Tokyo / Puma Fast-R 3 for his style but rates Cielo X1 3.0 in the top half-dozen carbon racers.
Best for: Race day from 5k through marathon for runners who love a big bouncy, propulsive ride and have efficient form. Better marathon option than v2 thanks to added stability.
An explosive, very fast carbon racer that excels for all-out efforts up to the half marathon but may be too wobbly and aggressive for marathon distance or slower paces.
Best for: All-out fast racing up to half marathon for runners who can handle an aggressive, less stable platform.
A phenomenally bouncy and aggressive all-out racer that is faster and more exciting than the Rocket X3; the reviewers' pick for PB attempts despite being less stable, less forgiving, and more expensive.
Best for: Advanced runners chasing PBs at 5K to half-marathon (and now marathon if form holds) who want the fastest, most aggressive carbon racer in the Hoka lineup.
