As of 2015, the Nike Dunk has been around for thirty years. It is considered to be one of the most iconic shoes out there, so much so that artist Kenneth Courtney actually dipped five pairs in 24 karat gold. That’s right, five pairs and they were all size eleven, so they are pretty much the definition of rare. These were purchased for $6,000 a couple of years ago but as you might expect, they are probably worth a lot more now.
