Nike is vowing to get to the bottom of the shoe fail that caused Zion Williamson's game-ending injury ... wishing the Duke superstar a quick recovery and promising to "identify the issue."
The Swoosh was front and center during the Duke/UNC game Wednesday night after Z-Dub's PG 2.5 shoe fell apart when trying to change directions 30 seconds into the game.
Zion spent the rest of the night in the locker room ... and Coach Mike Krzyzewski says his star is dealing with a right knee strain.
"We are obviously concerned and want to wish Zion a speedy recovery," Nike says.
