Nike ACG Ultrafly Trail Racing Shoes - ZoomX Foam and Carbon Plate for Trail Speed

The Nike ACG Ultrafly Trail refines everything that made the original great. More responsive ZoomX foam, a softer full-length carbon plate for smoother trail control, and a Vibram® Megagrip outsole built for durability and enhanced grip on wet terrain. Ultralight and built for distance on technical trails.

Ultra-Responsive ZoomX Foam with Carbon Plate

ZoomX foam delivers Nike's highest energy return with a stable trail feel. The foam is unwrapped in the heel for even better responsiveness, a detail that meaningfully improves the ride over the original. The full-length carbon fibre plate is softer than the original Ultrafly for better control on technical terrain without sacrificing the propulsive feel that makes a carbon plate worth having on trail.
