Unisex Zoom Ja Fly 4 (Sprint Track Spike)

Finish through the tape 1st in the Nike Ja Fly 4, a sprint spike made to help you set personal records in everything from the 60 to 400 meters. Nike’s lightest 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.

Benefits Include:

• Lighter, Faster:  An updated woven upper gives you security and containment at a significantly lighter weight than the Ja Fly 3, but with more breathability.
• Explode Out of the Blocks:  A completely new plate using computationally designed hexagons delivers stiffness in key areas to help you fly off the starting line and maintain speed throughout the race.
• Lace Up:  The Nike Racing shoelace is lightweight with notches and just a little stretch that allows for a secure fit that stays tied in all conditions.
• Designed for events ranging from 60m to 400m, including hurdle events
