6 reasons to buy

  • The carbon fiber plate integrated into the midsole gained some fans as it apparently helped in making each step as springy as possible.
  • The Flyknit upper was considered by most consumers as one of the best cover systems in the market because it secured the foot in a lightweight and breathable wrap.
  • Several runners were happy that this shoe accommodated their sizing expectations.
  • Purchasers have lauded the aesthetics of the Nike Zoom Fly Flyknit, stating that its looks were visually striking.
  • This shoe just felt fast, according to more than a handful of users.

4 reasons not to buy

  • Some people complained that the outsole unit already started to wear off after only a few uses.
  • Several individuals noted that this shoe’s profile was heavy for their tastes, emphasizing that it didn’t allow them to wear it for very long.
  • The removable nature of the insole caused it to shift around irritatingly, a few testers observed.

Bottom line

The Nike Zoom Fly Flyknit offered a lot when it comes to responsive performance on the roads. People were generally happy with the touted younger brother of the Vaporfly 4%. They welcomed the fresh looks, the fast heel-to-transitions, the high-quality midsole, and the breathable Flyknit upper. On the other hand, there were those who complained that the weight of this road shoe was more substantial than they anticipated; others weren’t happy with the easy-to-wear-off outsole and the way the collar chafed the ankles irritatingly.

Updates to Nike Zoom Fly Flyknit

  • The Nike Zoom Fly Flyknit is a running shoe that’s designed to accommodate neutral pronation. It is considered by many to be the little brother of the highly regarded Zoom Vaporfly 4% Flyknit running shoe from 2018. The difference between the Zoom Fly Flyknit and its older brother lies in the midsole, as this new product features the widely popular React foam, with its responsive and shock-attenuating nature aiming to make each step as reactive as possible.
  • The upper unit of the Nike Zoom Fly Flyknit is made up of the Flyknit Bootie, a one-piece wrapping system that evokes the feeling of being wrapped by a cloth. It is flexible and breathable, and it conforms to the shape of the foot as it bends and swells throughout the running session.

Nike Zoom Fly Flyknit size and fit

The Nike Zoom Fly Flyknit was designed to be true to size. Runners can choose a pair using their usual sizing expectations. When it comes to width, the available options are D – Medium for men and B – Medium for women. The semi-curved shape of this shoe mimics the natural outline of the human foot.


The heel portion of the Nike Zoom Fly Flyknit’s outsole is made up of a high-abrasion rubber. This compound’s purpose is to protect the midsole from the abrasive nature of the surfaces. It also provides traction as it is an inherent quality of rubber.

Foam rubber is used in the forefoot section. This layer is as traction-ready as its heel counterpart, but it’s also spongy and flexible. It could potentially add a bit more cushioning and spring, making each foot landing and liftoff as agreeable as can be.

The entire surface of the external pad features a polygonal traction pattern to heighten the shoe’s grip on the asphalt. The shallow grooves that trace these shapes serve as flex-points to encourage the natural bending of the foot.


The React is Nike’s top-tier proprietary foam technology. It is meant to be an answer to other companies’ cushioning technologies. This full-length foam has a responsive build that aims to strengthen each toe off and mitigate the landings. It has a somewhat substantial thickness that may agree with those who like to have intense running sessions.

A carbon plate is placed in the main React unit, reinforcing its entire surface. Its job is to help in gearing the foot towards an energized toe-off. It bends with the motion of the foot, then springs back into place when pressure is removed, thus giving the invigorated experience.

An insole is added to put some cushioning for the underfoot. This add-on can be removed or replaced with a new insert of the wearer’s choosing.


Flyknit is the material that’s used for the upper unit of the Nike Zoom Fly Flyknit. This material is likened to woven cloth, with a stretchy and airy build that’s reminiscent of socks. Runners can wear this running shoe without actual socks and still feel supported throughout the activity.

A one-piece opening allows runners to experience a consistent and all-encompassing wrap. The absence of the tongue unit lessens the risk of hot spots or material bunching.

A ghillie lacing system with flat laces and discreet eyelets helps to adjust the in-shoe fit without causing any strain on the instep.

Nike Swoosh logos are printed on the sides of the Zoom Fly Flyknit. These thin prints are meant to heighten brand recognition and help the rest of the upper when it comes to keeping the foot in place.

A pull tab on the heel part opens up the one-piece upper, allowing the foot to enter or exit the foot-chamber with ease. It also doubles as a hanging loop for when there’s a need to store the shoe on a hook or hanger.
