Nike ACG Ultrafly Trail

30% off

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-fibre 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.

  • The shoes are spectacular

    TerryS923911156

    These shoes are phenomenal. It took a little break in period but they absolutely sing. I’ve done multiple trail races including a 50k in them. I have over 280 miles on them and they still have pop and feel bouncy and fresh. The toe box is a perfect width. The stability (compared to the ACG zegama) is a little worse, but nothing to be concerned about. They are fast and have held up extremely well.

  • 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
