Been searching and testing out multiple running shoes that caters to my feet and running style and I believe that I finally found it in the Streakfly 2. Feels low to the ground with great cushion. I love the carbon fiber plate it comes with, I can feel the energy return, leading to less fatigue on my legs. Fit is snug, just how I like it. So if you’re a wide footer, I would get half size up if anything. Huge upgrade from the 1st Streakfly. Very satisfied, will be looking at another colorway in the future

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.

Perfect running shoes

Super fast and propulsive
Albert676069882 - Mar 24, 2025
The new go-to shoe for track races for this youth runner (no need to worry about WA / NCAA rules on shoes for track). For those who prefer flats to spikes, this is a tremendous shoe - promotes super-quick turnover, has some bounce, is comfortable, and is even lighter than the Dragonfly. Perfect 1500m / mile shoe, and will be testing later this season to determine if this works better than the Vaporfly for the 3000m (it should, but want to see how it works if runner fatigues a bit and loses some form, since these are aggressive). Sweet spot feels like 1:15-1:20 400m for a small ( < 5' ) runner.
Solid shoe

Super comfy and very light and springy but the fly plate feels kinda dead after a few meets (I run the 2mile and 1 mile and 800)
