Wear your Air. That’s the prompt from Nike Sportswear in advance of Air Max Day that’s set to go down on March 26th. One of the coolest yet promo pieces we’ve seen attached to the day is this gigantic shoebox installation that’s been spotted sitting out on the sidewalk in Shanghai. What’s inside? We’re not sure just yet, but hopefully that will be made clear when Wednesday arrives. Get another look after the break and then tell us in the comments what you’re wearing for this special day of Nike Air Max celebration.
