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.

Vibram® Megagrip Outsole for Wet Terrain

Vibram® Megagrip outsole is designed for durability and enhanced grip on wet terrain, reducing weight whilst maintaining traction as the miles pile up. This outsole handles the varied conditions technical trail racing demands with confidence.

Water-Drainage Upper

The upper is built for water drainage, puddles and stream crossings won't slow you down. Lightweight, durable, and breathable construction handles sustained trail efforts without excess weight or waterlogging.

Is the ACG Ultrafly Right for You?

Built for trail runners who want carbon plate propulsion and ZoomX energy return on technical terrain. The softer plate compared to the original gives better control on trails where stiffness becomes a liability rather than an asset. ZoomX foam with unwrapped heel construction delivers genuine responsiveness throughout, not just at toe-off. Vibram® Megagrip maintains grip confidence on wet surfaces where other outsoles compromise. Water-drainage upper handles stream crossings and wet conditions without waterlogging. If you want road super-shoe technology adapted for the specific demands of trail racing, the Ultrafly delivers the most trail-capable version yet.
