The was one of Nike's first Dunk collaborations. Do your research if you are unfamiliar with the Dunk ProB line...It was pre-NikeSB, and pretty much paved the way for the Skateboarding line they have today. When Alphanumeric was huge, I was a huge fan to say the least. I had posters, tons of clothing, stickers, backpacks, the works. I still to this day feel very fortunate to have this pair. One day I'll track down the other colorway, but this has always been the front runner in my opinion.
