The Nike ACG Ultrafly Trail is a carbon-plated super shoe engineered to redefine speed on the trails.

Built for ultramarathons and high-mileage training, it seamlessly fuses the responsive energy of ZoomX foam with a full-length carbon Flyplate. This updated version features a refined carbon plate with reduced stiffness, offering a smoother ride and better terrain feel without sacrificing propulsion.

Best for moderate, non-technical terrain and hard-packed paths, the ACG Ultrafly now boasts a more breathable upper and enhanced internal lockdown for a secure fit. The lightweight Vibram® Megagrip outsole provides elite traction while shedding unnecessary weight. With shallow lugs that transition effortlessly from pavement to dirt, it is the ultimate road-to-trail companion for runners seeking maximum cushioning and race-day speed over long distances.
