Nike’s ACG Ultrafly Trail features reliable traction, with the highest energy return we’ve experienced in a dedicated trail racing shoe

Race Through Trails With Reliable Grip and Nike’s Highest Energy Return Yet

We’re no strangers to Nike’s responsive and dependable ZoomX midsole foam. But in the ACG Ultrafly Trail, Nike’s technical All Conditions Gear racing shoe, the brand uses a new iteration of this foam. The reformulated ZoomX is lighter, faster, and more responsive, helping you fly up and down hills and across nearly any type of trail terrain.

The cushioning itself offers lots of responsiveness, but the shoe gets an extra boost from the flexible full-length carbon plate embedded in the midsole. This plate adds more energy return with each landing and toe off, as well as gives you more control and stability on technical trails.

The ACG Ultrafly Trail is built for long distance trail races and ultra marathons, so it’s crucial that it offers great grip and durability. The Vibram Megagrip outsole delivers in both of these areas, keeping you safe and secure in both wet and dry terrain. Vibram is also well-known for its durability across rugged terrain, so you can feel confident that you can go the distance in these shoes without early wear or breakdown.

The breathable mesh upper also excels in both wet and dry terrain. The lightweight material is well ventilated and quickly drains water to help feet stay cool and comfortable during long hours out on the trail.
