Nike ACG Ultrafly Trail
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.
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.
Don't worry about puddles or streams—the upper is made for water drainage. It's also lightweight, durable and breathable.
Tackle technical terrain with the full-length carbon-fibre plate. We reduced the stiffness compared to the original Ultrafly for better control on the trails.
Go the distance with Vibram® Megagrip outsole. It's designed to give you durability and enhanced grip on wet terrain.
Standard delivery costs €5 for non-Nike Members under €99 and Nike Members under €50.

Big improvement over last years Ultrafly
MichaelM710766495
The shoe has a very nice bounce to them when running and the fit is really good. Plenty of room in the toe box kept my feet comfy. I like the way the upper is made because it hugs the foot and does not let in small stones and dirt. Last years Ultrafly let dirt in like crazy and it’s really awesome Nike fixed this. Also all the color ways are really nice looking. I really like the blue color that I bought.
Nice Shoe

Very nice Shoe! The shoe does as it is advertised
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.
