Nike's billion-dollar man went all-out for Air Max Day -- LeBron James gave a tour of his massive shoe collection ... and of course, it's sick.
March 26th is a national holiday for sneaker heads ... because it's the anniversary of the release of the first Air Max shoe, which came out back in 1987.
In honor of the special day, King James opened up the doors to his shoe vault to show off his incredible collection.
And you know it's special when LBJ can barely contain himself going through all his boxes of new, classic, and unreleased kicks.
