Nike ACG Ultrafly Trail

Nike ACG Ultrafly Trail Trail Racing Shoes The Ultrafly Trail takes what you love about the original and refines it, so you can go the distance. The springy ZoomX foam is more responsive and the full-length carbon plate is softer for a smooth ride. The outsole helps reduce weight while maintaining enhanced grip as the miles pile up. Our newest iteration of ZoomX foam delivers durability, softness and responsiveness made for trail running. The full-length carbon fiber plate has reduced stiffness compared to the original Ultrafly. Vibram® Megagrip outsole offers exceptional traction on the trail with less weight. Strategically-placed lugs add grip for uphill and downhill racing.
