Air Jordan XXXIX Basketball Shoes If you want to play on MJ’s level, you have to put in the work to master the fundamentals: footwork, dribbling, passing, shooting. Packed with court-ready tech, this AJ39 is here to help you focus on laying the groundwork for your own game. After all, just because MJ lost a few toenails doesn't mean you should have to. Zoom Into Comfort ZoomX foam, Nike's lightest high-efficiency foam, conforms to the natural shape of your foot to give you soft and springy cushioning without weighing you down. Rock Solid Remember MJ's cross step? Of course you do. It influenced this shoe from the sole up. A built-in sidewall cupsole helps provide stability during lateral movements and allows for full engagement of the underfoot cushioning.
