Nike Dunk Low Pro SB Pigeon
Although they look fairly inconspicuous, the Nike Dunk Low Pro SB Pigeons are highly sought after by shoe fans. They were originally released in 2005, but in very limited quantities. The low release numbers eventually drove the prices up as the shoe began to gain popularity. With its low top style and the pigeon graphic near the heel, this shoe can now fetch upwards of $6,000 for a pair. They may not be the most striking pair on this list, but the price can definitely give you a case of sticker shock.
