Firm racing ride offers little easy-day comfort
  • Limited color choice (gray)
  • Sizing runs across a narrow band of men's sizes
  • What reviewers say

    Rated 4.7 out of 5 from 27 ratings, the Roadfly Zero is well received by runners who want a flat, fast shoe. Buyers tend to be racers and faster-runner types rather than casual joggers.

    What people mention
    • Ride feelPraisedRunners describe a fast, firm ride that rewards quicker paces.
    • DropMixedThe zero-millimeter drop suits forefoot strikers but demands adaptation from heel strikers.
    • GripPraisedThe Inov-8 rubber outsole is reported to hold well on road surfaces.
    • ComfortCriticisedSome find the firm racing platform thin for easy or long miles.
    • UpperPraisedThe engineered mesh is called breathable and secure.

    Questions and answers

    Is the Roadfly Zero good for heel strikers?
    It has a 0 mm drop, so there is no heel lift to soften landings. Heel strikers should transition gradually or look at a shoe with an 8-10 mm drop.
    What is the Roadfly Zero best for?
    Racing and faster runs. The FLYSPEED Pro foam and flat platform favor tempo efforts and race day over easy recovery miles.
    Does it fit true to size?
    It is listed in men's sizes 9.5 to 12.5 with standard and wide width options. Runners with wide feet should consider the wide fit.
    Is it a neutral shoe?
    Yes. It is listed as a neutral running style with no stability posting, so it suits runners without significant overpronation.
    What is in the box?
    One pair of Roadfly Zero running shoes. No insoles or extras beyond what ships standard are specified.
    Is the Roadfly Zero worth it?
    For runners who want a flat, firm, fast road shoe, yes. It gives you FLYSPEED Pro foam, a grippy Inov-8 rubber outsole and a breathable mesh upper in a zero-drop package. Runners who want cushioning for easy miles should look elsewhere.
