Air Jordan XXXIX PF Basketball Shoes The AJ39 isn't just another shoe you can hoop in. It's the bar being raised, a reminder of who taught everyone else everything they know. Lightweight, springy ZoomX foam stacks on a full-length Air Zoom unit to give you the responsive cushioning your footwork demands. The result? All play, no crash. Go ahead and keep 'em shook. 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.
