11. Nike Dunk High Pro SB "FLOM"
Leave it to legendary NYC graffiti artist Futura to create a Nike SB so rare that people had to wonder whether it really existed at all. The FLOM (For Love of Money) Dunk High was made in a run of just 24 pairs, and the currency-printed upper is an approximation of how much you'd have to pay for a pair of these now. For those who missed out (i.e. everyone), Nike dropped a LIVESTRONG version in black and yellow that saw a bit wider release.
