Nike ACG Ultrafly Trail

20% 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.

  • Awesome Pair

    n2nie

    Amazing pair of shoes. I’m a frequent runner on the road and trail (light to mild terrain). Very stable on the heel and very light. The shoes have energy return and you can feel it. It wants you to go faster. I have put in 30 miles and it feels great. Will buy another pair.

  • My new favourite shoe!

    Tariq7f0314c1740a465eb949cfaca3d8d477

    Love these! Stable, grippy, comfortable and FAST! I'm running 20km+ on dirt, gravel, grass and tarmac. Nothing too technical, its Surrey hills basically. The wide forefoot is good for me. The heel and the lacing are secure, I get a good hold in the heel without having to do a runners knot.

  • Great Purchase
