Nike has declared March 26 Air Max Day, which, of all the chimerical corporate holidays, is certainly one of the flyest. They've supplied us with a primer on the evolution of the Air Max, from the Centre Pompidou-inspired first iteration to the 2015 edition with its backward swoosh. There's also a bubbly little vid to illustrate the shoe's development, an animated take from the desk of Tinker Hatfield, the original co-designer and company icon. "I specifically went to Paris to see the city, but also to visit the Pompidou Center," Hatfield explains via Nike's blog. "It was a building turned inside out, with a glass skin underneath. Coming back to Oregon, I had meetings with the technicians who were working on the larger Air-sole units and I relayed my thoughts: Maybe we could also expose the Air-Sole technology and create a shoe that's like no other." The surreal, Pixar-esque video captures the imagination that went into the OG air bubble concept—we've watched it like four times already.
