Who should buy the Nike ZoomX Streakfly
The Nike ZoomX Streakfly is a must-buy for runners who:
- want a value-oriented option for 5K to 10K races
- are used to low-stack running shoes for a full marathon
- are new to running and want a racing shoe that can also be a great option for:
- track workouts
Who should NOT buy it
If you prefer a cushioned running shoe for marathons, go for the Nike Alphafly Next%. And for a versatile racing option, pick the Nike ZoomX Vaporfly NEXT% 2 instead.
Bolts you forward
It's "responsive," and "rebounding," everything about the shoe's ZoomX foam screams speed-ready. On top of this, runners highly appreciate the stiff midfoot shank that creates a snappy toe-off for a quicker pace.
More stack, less weight
Compared to the Nike Streak 6 (26 mm heel and 18 mm forefoot), the ZoomX Streakfly has more cushion (32 mm heel and 26mm forefoot).
Despite this, it still remains Nike's lightest racing shoe to date, barely weighing on the scale at 6 oz (170 grams in US M 9).
Cushy all day
Because it's more padded than the Streak 6 from Nike, runners say they don't mind using the ZoomX Streakfly the entire day.
This is also the same reason why many see it as a suitable option for marathons although it's only touted as a short-distance flat.
The Nike ZoomX Streakfly locks the foot in place
This is thanks to its secure heel counter, form-fitting upper wrap, and tongue. According to a horde of testers, the lockdown is "incredible."
The heel and midfoot are very snug, preventing slips and excessive rolling of the foot. They even compare it to a running spike's fit, particularly the renowned Nike ZoomX Dragonfly
A safe space for wide feet
Reviewers with broad feet are happy about the spacious toe box. It's roomy in terms of length and width.
Steady strides comin' through
Apart from giving this shoe a propulsive kick, the midfoot shank also keeps the Nike ZoomX Streakfly anchored. Its firmness keeps the arch supported every footstrike.
The Nike Streakfly latches to the ground
Sporting a similar outsole configuration to its Vaporfly and Alphafly siblings, the Streakfly from Nike is "very tacky," reported multiple experts.
If only looks could kill
Almost everyone agrees that the ZoomX Streakfly "nails it" in the style arena. The engineered knit looks like "modern art" with its stunning pattern.
So much so, several athletes say there's "nothing better looking" out there.
Forefoot is too wide for narrow-footed runners
Those with narrow-width feet recommend sizing down for a more dialed-in fit.
The laces could be better
The laces are too thin, especially compared to the Alphafly, Vaporfly, and the Dragonfly. This hurts the shoe's security, making it hard to cinch down.
