In support of Air Max Day 2016, Nike drops a documentary highlighting some of the world’s most passionate collectors of the Air Max line, dubbed Masters of Air.

The Nike SNKRS series profiles nine individuals from around the world, all of whom are obsessed with the Air Max silhouette… and have been for years. Volume 1 of the installment takes us to Nevada, London, Prague, Mexico and even Tokyo, to find out the stories behind each collector, browsing their shoes, and finding out what their Grail is.
