About the shoe itself in a nutshell

Nike came up with an innovative solution in the world of racing shoes at the beginning of 2022. It launched the ultra-light Streakfly, with an average sole thickness of only 29 mm, into the market of high-cushioned street shoes, which attracted great interest. The Streakfly is officially designed for 5-10 km street races, but it does not contain a carbon plate. The Streakfly therefore belongs to the non-carbon plate, aggressive racing shoe category, along with the Adidas Takumi Sen 8 and 9, the New Balance Super Comp Pacer, the Brooks Hyperion Tempo, and the Mizuno Mizuno Wave Emperor. It can be purchased at a price that is approximately 50% lower than its carbon plate counterparts. In the article below, I will explore the main features and parameters of this shoe and share my experience after almost a year of use.

Specifications:

• Sole thickness at the heel: 32 mm

• Sole thickness at the forefoot: 26 mm

• Drop: 6 mm

• Weight: 170 g in men's EUR 42.5 size (making it Nike's lightest racing shoe)

• Price: HUF 50,000-60,000 (on Top4running)

• Category: track partial distance, 5/10 km street race

The top is 8/10

The upper feels particularly spacious, especially in the midfoot and toes. It is extra wide, so runners with wider feet can wear it easily. The upper is extremely thin, as it is loosely constructed. So, in the case of lighter-colored models, a bright neon green or pink sock is visible from the outside. The tongue of the shoe is membrane-like, hugging the foot well. And the “gritty pasta-like” (am I the only one who sees them like that? :)) shoelaces, which are common with Vaporfly, are guaranteed not to untie… Thanks to its thin layer, it is well ventilated, which I especially appreciated in the hot summer heat, when my feet were sweating. The upper is so thin that you can even feel the caress of a soft breeze on your foot. The heel is completely padded. On the one hand, this prevents heel irritation, and on the other hand, it keeps the runner’s heel stable during movement. The heel collar is the perfect size: not too small, not too big. The only downside to the upper is that it doesn't provide enough stability during movement due to its thin material. My foot slid back and forth in the shoe quite a bit, which wasn't a problem for short coordination training (usually a NON-SPLIT-DISTANCE type of training that involves sprints of 150-250 meters), but it was energy-intensive for longer 1600-2000 meter sprints.

The midsole is 10/10

The midsole contains the familiar ZoomX foam along its entire length. Attention! This racing shoe does not contain a carbon plate, but you can still see a thin, plastic-like layer on the heel. This is the so-called Pebax plate, which ensures the flexibility of the shoe. Although the shoe can be easily folded in half, it is still particularly responsive, meaning it quickly adapts to the dynamics of the runner's movement. The lack of a carbon plate and the ZoomX Foam make the ground grip exceptionally soft and comfortable.

The outsole is 9/10

The outsole of the shoe is ribbed rubber, which I found especially useful on rainy days on the track. If you've ever struggled with the dilemma of whether to wear spiked shoes that provide adequate traction but pose a risk of slipping during a speed workout on a rainy May day between two races, or stick with slower, slippery, yet comfortable training shoes, then the Streakfly is for you! An extra thick layer of rubber running lengthwise on both sides of the heel ensures stability and durability.

Suggested use

I use this shoe exclusively on the track and in the gym for acceleration. It can be especially useful for running school exercises, which require an aggressive, responsive shoe. The grip provided by the ribbed outsole makes it a real experience when running in corners. When I do powerful, 30-meter standing start runs during the race season, I always use the Streakfly, because my Achilles tendon would hurt for about two days after using it.

Final Judgment

The Nike ZoomX Streakfly's price of around 50,000 is ideal compared to the prices of running shoes in 2025. In addition, it is the second most popular product line after the Nike Pegasus series. At the time of writing, it is available on store shelves in 17 different colors. This shoe falls into the optional category for a hobby runner. However, if you are a serious, competitive runner, then I would consider this shoe, as it is an integral part of a running shoe rotation that meets all your needs. For example, I recommend the following 4-piece running shoe rotation for you:

• Nike Invincible 3: for long runs and everyday training shoes

• Nike Zoomfly 6: for tempo runs, street races

• Nike Streakfly: for record-breaking interval training (sparing for your feet instead of spikes)

• Nike Dragonfly 2: for record-breaking races
