Pauly D -- I've Got $30,000 in SHOES!!!!

Pauly D just bought himself a nice little X-mas gift at a sneaker boutique in L.A. ... 4 new pairs to be exact -- and we're told, that's on top of the 350 pairs of Nikes he already owns!!!

Sources at Sportie L.A. tell TMZ, Pauly popped in last weekend and bought 4 pairs of Nikes for $120 each to add to his already gigantic sneaker collection ... estimated to be worth around $30,000.

Sources close to the "Jersey Shore" star tell TMZ, he flies out West regularly to score hard-to-find kicks ... and they don't come cheap!

401K's are so overrated.
