Nike‘s celebration of the iconic Air Max continues to dominate this month leading into the second annual Air Max Day on March 26. Joining in on the festivities is Spanish sportswear retailer sivasdescalzo, who has put up the largest ever Air Max wall at their store in Madrid. The unique exhibition features over 70 silhouettes of the classic sneaker, ranging from old to new. Perhaps even more impressive is the fact that 20 of them are original releases they have borrowed from Luis Miguel “Jumi”, a collector who was kind enough to lend a few of his most precious assets. The world’s largest Air Max Wall will be on display until April 13 at sivasdescalzo Madrid. Take a peek at a bit of sneaker history below.
