A ZoomX trail racer with a carbon plate and Vibram grip, suited to sustained fast running on smoother trails and gravel.
Checked US price · 2026-09-19. Before tax and shipping. Unisex Aloe Verde SP listing, checked September 19, 2026. Available sizes may vary.
The ACG Ultrafly Trail combines soft ZoomX cushioning, a carbon plate and Vibram grip for sustained fast running on smoother trails and gravel. Its focus on runnable terrain makes it an appealing option for trail workouts and races where you can maintain a consistent pace. Shallow tread is a limitation in deep mud, and the upper can become warm in hot conditions. Fit reports range from a roomy forefoot to a closer hold, so try it with your intended trail socks rather than assuming a familiar Nike size will work.
