The Ultrafly Trail positions itself as a long-distance trail racer, combining springy ZoomX foam with a full-length carbon plate for propulsion over extended, technical efforts. It's a specialist race-day tool at a steep $260, best justified by runners chasing speed on gravel and mixed terrain. Independent lab specs (weight, stack, drop, lug depth) are absent, so verify fit and firmness before committing.
Responsive, springy ride from ZoomX foam and a full-length carbon plate, tuned for speed while retaining cushioning that holds up over longer distances and technical trails.
Wide toe box with secure heel lockdown, but the midfoot reportedly runs tight—wider-footed runners should consider sizing up.
Competitive trail runners wanting a plated, cushioned racer for long and technical events on gravel, dirt and mixed terrain.
You want a budget option, need a roomy midfoot, or require verified stack, drop and lug specs before buying.
