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 fiber 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.

My new favourite shoe!

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

Fabulous trail running shoe. I run 5-10k trail runs three times per week, so a fairly amateur runner. I have been using the Pegasus Trail 5 and Peg 4 GTX mainly this year which are both great shoes. I wanted to try these due to the full ZoomX, carbon plate and Vibram sole. I was hesitant because a lot of the reviews online (incorrectly) paint this as a focussed race shoe only. It’s not. It’s a comfortable, well cushioned everyday trail trainer as well as something you can push for a pb in. The carbon plate is not intrusive and with faster/longer strides really returns something extra. Cut a minute from my 10k pb two weeks into using them. Construction is solid, comfort is excellent. Super stable, grippy on grit and loose surfaces. I take a size 9 in regular shoes but always order half a size up in running shoes and that’s perfect for these too. My road running shoes are Vomero Plus and they too have full ZoomX but feel nothing like these at all, these are way more stable and less marshmallowy in their cushioning.
