Nike Ja Fly 4 Track Spikes

Finish through the tape 1st in the Nike Ja Fly 4, a sprint spike made to help you set personal records in everything from 60 to 400 meters. The lightest Nike Sprint spike sports a revamped plate for enhanced stiffness and an updated upper for better breathability, so you can stay focused on doing your best.

Woven Upper

Supplying your feet with an exceptional layer of breathability and comfort, the Ja Fly 4 Track Spikes utilise an updated woven upper. This upper construction supplies your feet with a great level of security and containment, to ensure you remain comfortable preventing distraction during intense competitions. It's significantly lighter in weight than its predecessors, keeping you light on your feet, and allows a great deal of airflow to travel around your shoes to keep your feet feeling cool. The materials are also moisture-wicking, meaning the uppers of the Ja Fly 4 Spikes will effectively wick moisture from the surface of your skin, keeping you dry and comfortable when racing. Completing the uppers are a lightweight Nike Racing shoelace, with notches and a small level of stretch to provide you with a secure fit, also meaning they remain tied up in all conditions.

Seven-Spike Outsole

Supplying you with underfoot traction and support during competing, the Ja Fly 4s have a newly updated plate and removable seven-spike outsole. The plate uses computationally designed hexagons which provide you stiffness in key areas of your foot, which therefore help you to fly off the starting line and maintain that speed throughout your race. Additionally, the removable spikes supply you with underfoot grip and traction on the track, keeping you focused on the course ahead.
