"Those ZO2s I was playing in, they was not ready," Ball admitted on Josh Hart's 'LightHarted' Podcast.

Ball -- who was playing for the Lakers during the BBB shoe era -- says he would bring 4 pairs of the shoes to games because he knew they would break and he had to switch them out every quarter.

"If you literally had my shoes from those games, they just exploded, bro."

If you recall, BBB initially offered the ZO2 Prime shoes to the public for $500 a pair in 2017 -- but later announced they were scrapping the original design in favor of the ZO2 Prime Remix shoe, a completely different sneaker.

It seems obvious now why BBB made the change. Unclear if any of the faulty shoes were actually sent to customers.

When asked why he wore them -- even after he knew they were defective -- Ball explained, "Because they were my shoes, I had to debut 'em."

Ball says he actually HATED wearing the shoes and implied that his game suffered as a result.

"And, it's crazy," Ball says ... "Right when I switched my shoes, magically, I got good again."

Ball says he kept the secret about his crappy shoes to himself to protect the brand.

Things eventually went south with the Big Baller Brand -- with Lonzo's manager later telling customers to throw their shoes in the trash ... and Lonzo himself eventually covered up the BBB tattoo he had on his arm.

Still, LaVar Ball claims the brand is still alive and he's looking to relaunch at some point in the future.
