Here's a rare Nike SB Dunk sample that even the most seasoned of collectors probably haven't seen.
The "Sea Crystal" Dunk Highs are one of the most coveted Dunk colorways, but this sample isn't quite the same as the pair that made it to retail.
Not only are the shades of blue a bit different, but the color blocking is completely flipped, with a lighter tint of off-white appearing on the overlays here.
If you're feeling these, the bad news is that they aren't going to come cheap—the eBay auction just ended at $800 with no bids. They haven't been relisted yet, but you can always try to negotiate a deal with the seller here.
