Jadakiss -- My Jordan Collection Is Epic ... 'A Couple Thousand Shoes'

There are sneakerheads ... and then there's rapper Jadakiss ... who tells TMZ Sports his Air Jordan collection is INSANE ... consisting of more than 2,000 SHOES!!!!!

Jadakiss was leaving a Footaction in NYC -- when he told us another shocker ... he knows other celebs with an even BIGGER Jordan collections than his!!

Of course, Jordans have become huge collectors items over the years -- with some pairs valued at more than $3,500!!!

But get this ... while Jadakiss has paid for a large chunk of his collection with his own cash, the rapper has in the past that MJ sends him boxes of shoes for free ... because he's a fan.
