Super lightweight and very bouncy race day shoe. The materials are very light and feel very comfortable and nice on foot. The breathability is also very good and is not lacking. The bounce and propulsion in each step is very noticeable while running and will easily maximize PR times. Sizing was true to size, but if you have a wide foot you may want to try them on to get proper sizing for your perfect fit. I had a lot of fun running in these and would definitely recommend as a go-to race day shoe!

Performance Approved
The handwritten number on the midsole salutes the wear-testers who put these shoes through our rigorous test process to give you the best performance possible.
Full Speed
We integrated a full-length carbon fiber 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.
Breathable Upper
We reduced the internal components of the upper to help keep it as minimal as possible. Breathable, engineered zones of mesh offer comfort.
Sticky Outsole
The outsole is made of a thin, sticky, webbed substance that helps reduce the weight of the shoe while still providing optimal traction.

#teamnikeAwesome 5k running shoes
Trevor - Apr 25, 2025
I have been able to try out the Streakfly 2 and it's been absolutely awesome. Bouncy feel with a good amount of cushion and a nice thinner upper the breathes very well. I wouldn't use this for longer runs but for a 5k or 10k it's absolutely amazing.

#teamnikeNike ZoomX Streakfly 2 Men’s Road Racing Shoes
Nike Streakfly 2 - Apr 25, 2025
The first thing I noticed about the sneakers was how light they were. They also looked fast and sleek. The fit was snug, but in a good way; it was almost sock-like. The laces have these little grooves in them that secure the laces when they are tied. That’s a very nice touch! When I took my first step, I could feel the ZoomX technology, but it was softer than my current Nike Vomero 17s which also have ZoomX. I noticed that I felt extra support from the forefoot all the way to my toes. Now to the plate in the midsole; that was something I had never felt before! I’m not familiar with how the plate works, but I can describe how it felt. It seemed like with every stride I took the plate absorbed the energy I gave it and as soon as my foot was no longer giving energy, the plate gave the energy right back to me. It was an incredible feeling. I really noticed it as I was going uphill. My runs felt easy and fast without much effort. It’s a fun sneaker to run in. There was one con about this really cool sneaker though. There is deep groove that runs almost the length of the outsole where you can see the plate. I had a couple of instances where rocks would get stuck in the groove and I would have to stop running to get them out. This could just be specific to me because of the different types of surfaces I was running on. With this being a road racing sneaker, it may not be meant for everyday use and heavy mileage. It’s sweet spot is 1 milers to the 10k. Overall, this sneaker is awesome!
