Nike Ultrafly

Nike Ultrafly review: what runners say

Fit

True to size with a wider-than-usual-for-Nike platform and a spacious toebox. The midfoot runs narrow; some runners report the toes sitting too close to the tip.

Feel

ZoomX with a carbon plate delivers a responsive, fluid ride on firm terrain. On technical ground, the soft foam and lateral stiffness compromise stability.

Durability

Vibram Megagrip provides solid grip and outsole longevity. ZoomX foam tends to break down faster than traditional compounds; the Vaporweave upper holds up on moderate trail but degrades on abrasive terrain.

Best for

Race-day shoe for non-technical trail: hardpack, dirt roads, fire roads. Suited to runners transitioning from road to trail who want comfort over long distances at a sustained pace.

Weak points

Limited versatility: unstable on off-camber and technical terrain, with ankle-roll risk flagged by multiple sources. The $260 price point is widely considered steep given the narrow use case.
