Great next-gen racing flat. Very squishy, but it somehow has great energy return. I’d prefer the foam to be more firm for the faster efforts I do in this shoe, but I don’t think the squishiness impacts energy return. you will not heel strike in these if you run how you’re supposed to in them, so the heel foam is just about useless—I’d like them to chop more of that off. For reference, I’m doing 5:00/mi intervals in these. Lugged grip is awesome for a wet track. DO NOT PURCHASE if you have bad mechanics/are slow. These are not for you. I run in a 9 across all Nikes and Saucony, and these fit similar.

Full Speed
We integrated a full-length carbon-fibre Flyplate that delivers a propulsive feel. It helps you smoothly transition through every stride and tackle turns with confidence.
Optimal responsiveness
ZoomX foam, our most responsive foam, provides optimal responsiveness. The result is a shoe so light, it feels like it disappears on your foot while still helping you reach your fastest pace.
Sticky outsole
The outsole is made from a thin, sticky, webbed substance that helps reduce the weight of the shoe while still providing optimal traction.

Next-Gen Racing Flat, but Squishy

tearing apart at the heel

I bought these shoes last week. They’re super light, well-designed, and breathable. However, my expectations for Nike products are much higher, as I’ve been wearing Nike shoes for over 20 years. I was surprised to see them tearing apart at the heel after just one 5K run, especially since I’m not even a heel striker. The shoes were basically done after one use! The heel plastic is too soft. So, how am I supposed to use them for an entire year?
