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.

    Shoes is good, was happy for the discount. Not really planning on buying one since I have already a lot of shoes but I just can't get the discount go LOL. Looking forward for more quality, good design shoes

    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.

    Comparing to my AF3’s, these are superb. Very soft ZoomX foam. Very stable. Toe box is roomy. Carbon plates has been upgraded and helps with faster movement without hurting ankles. Doesn’t hurt my pinky. I love that the comfort it gives is between the Vomero 18’s and Plus. I can even use this for casual long walks. Ankle lockdown is great. I got the Baltic Blue and design wise, it is very beautiful. Such a great flex with how it looks. I got the mens US 9.5 and the fit is perfect. Could be better if some of the patches are reflective such as the ACG logo on the back, the Nike Swoosh. Overall it’s a 10/10.

Lightweight speed, grip and energy return, come hell or high water.
