Happy Air Max Day, everybody! In 1987, Tinker Hatfield unveiled the iconic silhouette that would go on to change sneaker history forever. Celebrating nearly three decades of design and innovation, Nike got together with Italian automobile manufacturer Fiat to collaborate on a series of vehicles that have been spotted around Seoul this week. The body of the cars have been made to look like various Air Max models while sitting on top is a giant corresponding shoebox that's nearly as big as the car itself. Take a look at the awesome displays below.
