Use – The Nike Zoom JA Fly is a running spike that’s perfect for sprinting meets. These can range from 100 to 400 meters. Because it excels as a multi-purpose track spike, it can also function in hurdles.
Spike Type – There are eight Christmas tree spikes assigned to the sprint shoe. These spike pins compress on the track surface that yields robust energy return to the foot, powering the pace of the runner.

As one of the best sprint spikes released by Nike, the Zoom JA Fly is loaded with reliable technologies. These help maximize the performance of the runners on the tracks.
One of the integral features of the track running shoe is its incorporation of synthetic leather upper—combined with Nike’s Flywire technology. This mix allows for a featherlight, propulsive ride.
Zoom JA Fly offers plush cushioning
A low-profile Phylon midsole also enables plush cushioning to the underfoot. It keeps weight down to an absolute minimum for ultra-light platform composition.
The Nike Zoom JA Fly only runs in men’s sizing measurements. It is designed using the standard width. Thus, women are advised to deduct 1.5 from Winter usual size preference to secure precise fit and size.

This technology is made of compressed EVA foam pellets that are expanded via heat and then cooled into a mold.
It provides responsive cushioning and delivers the rebounding properties needed during the run. It is also very light, cohering to the overall design principle of the Nike Zoom JA Fly.
Nike Zoom JA Fly offers breathable security
Composed of synthetic leather material, the upper of the Zoom JA Fly serves featherlight coverage. It locks the foot in place along with the running shoe’s Flywire technology. It is composed of highly durable laces which permit a dialed-in fit.
This upper construction also allows for breathable security, promoting a healthy foot environment. This, in turn, disables odor and bacteria from flourishing within the foot chamber.
