Here is a rarity, the Nike Dunk High Pro SB Iron Maiden Sample, which were created as a nod to British Heavy Metal band Iron Maiden. The sneakers feature a clear swoosh along with Iron Maiden artwork on the side of the sneaker. The heel of the sneaker features the words Iron Maiden on the back. Word has it that only 24 pairs of the sneakers are in existence with all of them going to people at Nike and Iron Maiden. These sneakers hit the open market when a Nike employee put these up for auction. When Nike found out about this, he was promptly fired. There is no planned release date for these kicks.
