Nike ACG Ultrafly Trail

2 899 kr

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.

  • Great trail shoe for everyday runs

    PeerS502787967

    Been running in these for about two months now and really like them. Great grip on gravel and dirt roads, very comfortable to wear and they feel really stable. Also a big plus: they come in proper large sizes, which is not always easy to find. Overall, a really great shoe. 5 stars

    Schiene

    Ich war selten so hin und her gerissen zwischen Wow und geht gar nicht bei einem Schuh. Also Dämpfung, Grip und Farbe/Style sind herausragend. Er ist ein stylischer bequemer Hingucker und auf Schotterwegen bergauf wie bergab mit super Traktion ausgestattet. Das nahezu Luftdichte Obermaterial hingegen geht gar nicht. Schön ja, aber null Atmungsaktiv und viel zu hart. Im Fersenbereich hat man zu wenig halt, was den Schuh nur auf nicht allzu schwierigen Trailpassagen funktionieren lässt. Sollte es zu steinig werden und die Wurzeln zu groß, ist umknicken vorprogrammiert. Last but not least die Schnürleisten. Hart, Kunststoff und somit nicht ordentlich und bequem schnürbar da die starre Leiste sich nicht an den Fuß anpassen kann und dazu wieder eine viel zu lange Zunge. Machen leider aktuell fast alle so. Ein Alltagsschuh bis hin zu leichten Trailläufen der sehr schick ist, aber für das oberste Regal ist dass nicht genug.
