Nike also places a Carbon Flyplate between that ZoomX and fabric-wrapped midsole to help deliver smoother transitions.
In an interesting move from Nike, it included a Vibram Megagrip outsole to deliver off-road grip.
Nike typically uses its own outsole technology, which Ive had mixed experiences with.
This isnt an aggressive, speed shoe that delivers an extremely bouncy feeling.
Its different, but in a good way.
Ive also been mixing in some road time and taking in some lighter, more challenging trail terrain.
The first thing you notice about the Ultrafly is that it doesnt feel built like Nikes other trail shoes.
Thats largely down to the roominess of that toe box.
Unfortunately, it just doesnt deliver the same lively ride.
What it does instead is provide comfort and thats really what you need over longer distances.
As a package, its smooth and stable.
Overall though, its a shoe that Ive enjoyed spending time in.
