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. Our 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. 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.
