Nike ACG Ultrafly Trail

Ultralight cushioning and enhanced traction power every stride in the Nike ACG Ultrafly Trail. Refined for longer, smoother miles on technical terrain.
Building on what runners loved in the original, this update features more responsive ZoomX foam with an “unwrapped” heel for snappier energy return and a stable trail-ready feel. A full-length carbon-fibre plate has been tuned to be more flexible than before, improving control and flexibility when the trail gets tricky. The lightweight, breathable mesh upper is engineered for durability and quick water drainage, so puddles and stream crossings won’t slow you down. Underfoot, a Vibram® Megagrip outsole trims weight while delivering confident, long-lasting traction—especially on wet surfaces, so you can go the distance with grip you can trust.
