Lonzo Ball finally unveiled his long-awaited Big Baller Brand shoe -- and it can be yours if you wanna spend $500!!!!!!

The shoe -- called the ZO2 -- is more expensive than ANY SHOE currently for sale on the Nike.com online store (for the record, Nike's priciest shoe is the Air Jordan 5 Retro at $400). 

And that's not all ... Lonzo's BBB brand is offering a premium collector's version of the shoe for $500 more ... in which you get an autographed pair and a special display case with LED lights. 

Lonzo's father, LaVar Ball, has said he plans to move forward with BBB because no major shoe company would give him the "true partnership" he wanted.

Big Baller Brand is also selling sandals for $220 a pop. BBB says they're they're the "ultimate in style and comfort" feature a "non-slip Crystal Gold outsole."

LaVar is clearly gunning for upscale clientele -- we'll see if he hits his target. 

For comparison ... the most expensive shoe on the Under Armour site is UA Curry 3ZERo ($120) and Adidas' priciest pair is the ADO Crazy Explosive shoes at $200.
