Sneaker stores across the globe are taking part in Air Max Day with all sorts of events and in-store builds dedicated to visible Air.

Foot District in Spain has one of the cooler trinkets offered as part of the celebration in its miniature Nike Air Max Zero. The tiny shoe is 3D printed, hand painted, and exclusive to the store.

Anyone in Madrid can stop by the store to see these Air Max models being printed live in the lead-up to Air Max Day.

Foot District is also launching the Nike Air Classic BW this weekend with a limited run of special wooden boxes.
