Nike once again takes center stage this weekend with both its celebration of March Madness and the culmination of its month's long celebration of the Air Max, "Air Max Day." In addition to Nike, Jordan and adidas are dropping a couple of key releases this weekend.

The finale to the Air Max celebration starts on Thursday with the release of the NikeLab Air Max 97 x RT and on Friday, Nike Basketball draws inspiration from the NCAA Tournament to release the "Time to Shine" pack.

Heading into Saturday, adidas links up with the United Arrows and Sons once again to release a collaborative adidas NMD_CS1. Jordan is dropping two retro sneakers on Saturday which will include the Air Jordan 6 Retro GG "Pantone" and Air Jordan 4 Retro "Motorsports." The prequel to "Air Max Day" will also feature the Nike Air Max 1 "Master" and Marc Newson's take on the Nike Vapormax.

Nike officially celebrates "Air Max Day" on Sunday with the introduction of the Nike Air Vapormax in three colorways including a "Triple Black" colorway.
