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’s also engineered to be 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 to yield a robust energy return to the foot, powering the pace of the runner.
Spike Plate - For aggressive, unparalleled traction, a rigid plate is affixed to the track spike. It houses the detachable pins of the sprint shoe for multi-surface traction. It also exhibits high-strength properties for added durability.
In order to serve its pledge of being 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.
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 measurement. It is designed using the standard width. Thus, women are advised to deduct 1.5 from their usual size preference to secure precise fit and size.
There are several components that directly affect the fit of the Zoom JA Fly. For one, its Phylon wedge allows for a supportive, well-cushioned fit. Its Flywire technology permits durable, adjustable wrap. Lastly, its synthetic leather upper has foot-conforming abilities that are integral for security and lockdown.
Running full-length on the outsole of the Nike Zoom JA Fly, a stiff yet light spike plate is furnished. It hosts the receptacles and risers of the sprint spike for unrivaled traction. Moreover, it keeps the runner up on the toes for explosive sprint performance.
Just like the Nike Zoom Mamba 5, the Zoom JA Fly is equipped with a Phylon wedge. This technology is made of compressed EVA foam pellets that are expanded via heat 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.
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.
