In sneaker culture, there will always be Player Exclusives and samples that never release to the general public. With the rise in social media now, it's not uncommon for these kinds of sneakers to surface on the 'net even if they never actually go into production. Sole Collector rounds up 10 very rare sneakers from the last five years where a sample emerged, but was never actually released (those "Denim" IIIs, tho). View the complete list on Sole Collector and just wonder what could have been.
