Aside from the trade show going on at Outerspace in Barcelona right now, the main event has to be the incredible Ball Sneaker Expo Exhibition that is on display at the event. For as far as the eye can see, there are rows of wooden crates with glass windows that reveal a collection of some of the most incredible rare and vintage Ball Sneakers ever seen all in one place. Some of the kicks on display date back over 20 years and many are still complete with their original boxes and packaging. As you might expect, Nike kicks dominate the show with both OG classics and newer offerings like some Womens Nike SB models. Aside from Nike, many other brands are represented with some vintage throwbacks from Adidas, Reebok, Converse, New Balance, Asics and more, as well as some old-school skate models from Vans and Airwalk. Keep reading after the jump and take your time scouring a boatload of pics of all the wonders contained in this sea of crates. Via glltn.
