And, get this ... Zion rocked a pair of Puma RS-0 "Video Game" kicks during a Summer league game earlier this month, and our sources tell us that's no coincidence.
We're told Nike is aware of the competition and is making a hard push to get a deal done with Williamson first. As one source puts it, "He's the #1 priority."
Remember, Zion did have one bad experience with Nike in college ... when his Nike PG 2.5s blew out during the opening seconds of the Duke vs. North Carolina game.
Fun Fact: The shoes were never seen in public again after that incident ... and Ken Goldin from Goldin Auction told us he thinks the kicks could be the most valuable collegiate sneakers of all time ... worth more than $250,000 if they ever hit the auction block!!!
The NBA season kicks off in October and whatever brand signs Zion is going to want him to wear their sneaker on opening day ... so, ticktock.
