Nike ACG Ultrafly Trail

$260

Ultralight foam and enhanced grip fuel your trail speed.

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.

ZoomX Foam

Ultra-responsive ZoomX foam midsole delivers Nike's highest energy return with a stable feel for the trail. The foam is “unwrapped” in the heel for even better responsiveness.

Breathable Mesh Upper

Don’t worry about puddles or streams—the upper is made for water drainage. It’s also lightweight, durable and breathable.

More Flexibility

Tackle technical terrain with the full-length carbon fiber plate. We reduced the stiffness compared to the original Ultrafly for better control on the trails.

Enhanced Grip

Go the distance with Vibram® Megagrip outsole. It’s designed to give you durability and enhanced grip on wet terrain.

Speedy yet none forgiving
IanS122928791May 20, 2026
Raced in the first version of the Ultrafly's and thought these would have been an improvement to them. I'll give it to Nike that these are a super snappy shoe with a great upper fit. The Vibram outsole is grippy as well -- no issues there. The main issue I'm having with them is the midsole is even stiffer than the first version! I've gotten 30 miles in the shoes so far and am hoping that it's just a break-in issue, but my feet are so sore after running in these that I cannot fathom doing any ultramarathon distance race in them, especially on technical terrain.
Poorly Designed for long distance

Fascinating how a long distance trail shoe has no room for expanding with your feet. considering the R&F budget. lets say your 40 miles in to a 100 mile race. how can these adapt to your feet like most other shoes. poor design.
Love them

Amazing shoe on trail. It doesn't feel heavy and has a great solid platform to help with stability.
