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.

Finishing is not good
NipunaDaminda982906245
Even though the shoe is comfortable, the finishing of the pair that I received was not good. There is a visible gap between the sole and the upper on the right side of the shoe, beneath the Nike Swoosh. The Swoosh also appears to be separating into two parts. Expected a better quality for the price.
Awesome Shoe From The First Wear! Want Another Pair!

I fell in love with these after the first wear to the gym yesterday. The footbed is stable and comfortable, and you can instantly feel the grip the bottom has on the ground. I have been training for Hyrox and I may actually test them out in my simulation this saturday!
AMAZING

I bought because my doctor recommended them, after so many problems with my feet (stress fracture 5 metatarsal and arthritis in my big toe, the pain is insupportable) The shoes are so light weight and very comfortable, I am using Nike acg zegama trail, for my longest run, and the nike ultrafly for short run, no more than 3 or 4 miles, because the drop for me is too high 8.5 and I need more time to adapt. I regularly use running shoes with 4 mm drop, and it is perfect for me, if nike can make nike ultrafly with 4mm drop, for me will be perfect, but I recommended this product.
