Nike Air Foamposite model has been a fan-favorite for a couple of decades and in 2013, the brand has taken the popular silhouette into a new direction in terms of its concepts and overall style. The more modern editions are very different from what we're used to seeing from Nike and while we're sure sneakerheads will flock retailers to cop 2013's remaining Foamposite releases, there are quite a few that never saw a retail launch and today SneakerWatch sheds some light on some of those samples and PE's.

Some of the more notable styles include "Chocolate" Foams, two "Galaxy" samples, New York Knicks Spike Lee PE, Comic Strip sample, an Army Camo sample, and Blue Marble sample that is absolutely incredible.
