Nigel Sylvester and Jordan Brand have been on quite the collaborative hot streak as of late: they released an Air Jordan 4 RM “Driveway Green” in July 2024, followed by an Air Jordan 4 RM “Driveway Grey” in August 2024, and, most recently, an Air Jordan 4 “Brick By Brick” that touched down just last week. Thanks to their clean colorways, rich storytelling and compelling in-person activations, from a literal “brick truck” to a takeover of a mom-and-pop sneaker store in Sylvester’s hometown of Queens, Sylvester and the Jumpman have been able to cut through the chaff of the modern, oversaturated footwear collab sphere — and they might not be done just yet, as images of a co-created blue Air Jordan 4 have begun to make the rounds on social media.

The pair, originally thought to be little more than a color-flipped Photoshop job, is shrouded in mystery. It may be an early sample that was never meant to see the light of day, a special one-off for Sylvester and his crew, or even potentially a well-constructed bootleg (neither Nike, Jordan Brand or Sylvester have issued any official comms about the shoe at the time of writing). Apart from its bright blue color scheme, it’s identical in detail to the “Brick By Brick,” as it features a durable rubberized mudguard with a small Swoosh logo, reflective material behind its midfoot cage, and, of course a “Bike Air” hit on its heel.
