Streakfly 2
Nike's short-distance racer pairs a thin ZoomX midsole with a full-length carbon Flyplate at around 128 g. Reviewers rate it for mile to 10K racing and fast reps, not everyday running.
What's new: Adds a full-length carbon Flyplate, which testers found gives a stiffer, more responsive toe-off than the first Streakfly.
About the Streakfly 2
At the short end of Nike's racing range, the Streakfly 2 is built for 5K and 10K road races, intervals and track-style sessions. Next to the Vaporfly 4 it is lower and lighter, and it is aimed at shorter distances.
The biggest change from the first Streakfly is a full-length carbon plate, the Flyplate, which the original lacked; it sits behind a large central cutout in the midsole. The ZoomX foam is the same supercritical PEBA formulation RunRepeat identified in the Vaporfly 4, and the heel is lower than before. Rubber is limited to two small heel pods and a forefoot section, leaving the midfoot exposed, while the engineered mesh upper uses wire lacing, a very thin ungusseted tongue and a fixed insole. It weighs 128 g in a men's UK 8.5 and has a 4 mm drop, suiting it to 5K and 10K racing.

- Road Trail Run 8.8/10
- RunRepeat 88/100
The reviews in briefRoad Trail Run's Bryan Lim and Ryan Eiler found the Nike Streakfly 2 light and snappy at fast paces, though harsh and inefficient when slower. Doctors of Running's Andrea Myers and Matt Klein loved it for mile to 5K racing but flagged a narrow upper, while RunRepeat's Carlos Sánchez measured a snug, low toe box.
- Positive: Very light and snappy at mile to 10K race paces
- Positive: Stiffer plate gives a more responsive toe-off than the original
- Positive: Secure, locked-in upper and good grip on dry roads
- Mixed: The low drop feels near zero or even negative to some testers, which can load the calves
- Negative: Harsh and inefficient at easy paces, so very limited versatility
- Negative: Exposed foam and outsole raise durability worries

What it feels like
Fit
True to size
Testers found it true to size but narrow and low volume; one went half a size up, and those who size up in the Vaporfly 4 may need to here too.
