Overall: This shoe is a must for those trying to increase speed. The aggressive design makes it a skip if you’re a beginner runner. Ideal for anything less than a 5k. I would leave the 10k running in these shoes to experts only. Not sure if its the design or placebo (probably both) but I’ve been running a consistent 3 miles in other brand shoes and in these and I shave of 1 min 30 sec per mile in these shoes. I do think because of the design, I was leaning more forward and running faster to get the benefit of the carbon plate spring. Comfort: right off the bat, this shoe will wow you with how light it is - without question the lightest pair of shoes I’ve ever worn. The cushion feels great with s nice spring due to the carbon plate while running. The shoe is narrow but with the upper, hugs your foot like a sock. I’ve been running a few times with these shoes and I go sockless. Look: I LOVE the way these shoes look. They are oh no aggressive with the perfect Nike logo on it. Durability - To be seen. I’ve only worn them a few times but the soles are grippy and so no signs of wear yet. The laces are top notch with little ridges that ensure they stay tied up while running.

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.

#teamnikeNike Streakfly 2 Men's Road Racing Shoes for the Win
Mom of 5-15k Racer - Apr 28, 2025
The Nike Streakfly 2 Men's Road Racing Shoes are built for the road races around the Tampa Bay area. The carbon fiber Flyplate and ultra-responsive ZoomX foam midsole and minimal upper helped my guy get through The Gasparilla 4 race, 2 day weekend. The shoes are true to fit, light and airy, and propelled my racer to finish and achieve his personal record without exhausting his legs and feet afterwards. The design is just cool; the colors are vibrant and are fun to style. The best part of the shoe is the rocker foam sole that enabled a speedy pace to the finish line. We are looking forward to utilizing these shoes for more races throughout the year including charity runs and ending with the St. Pete Run Fest!

#teamnikeWish I would’ve sized up
Andie - Apr 28, 2025
I wish I would’ve sized up. I am normally a 7 (8.5 womens) but sometimes need to size up to a 7.5 (9 womens) for a better fit. This was one of those times. I’m in between sizes but def should have sized up. They are super lightweight and give you that extra pep in your step. After a little bit on my run I felt my toes being sore but I attribute that to being just a tad bit small. Overall a great shoe but I felt like I would’ve gotten more out of it if I had sized up
