Nike slipped a pretty interesting Kobe detail into this year’s Mamba Invitational in Los Angeles, and it may be our first look at something new coming from the line.

The event included an exhibit looking back at the design and performance work behind Kobe Bryant’s signature sneakers. One of the main pieces on display was “Sole Obsession,” a mixed-media installation created by artist Troy “TYP” Murray for the Invitational.

The artwork features molded casts of 13 Kobe outsoles, spanning the Kobe 1 through the Kobe 11 and the Kobe AD. Sitting alongside those familiar designs is one sole that hasn’t been seen before, and it appears to be tied to a future Kobe project Nike is currently working on.

Murray built the piece around the details that shaped Bryant’s footwear over the years. Lining up the outsoles shows how the series changed from model to model while keeping performance at the center of each design.

That mystery outsole may be more than an unused concept, too. Kobe Brand VP and GM Dan Sunwoo confirmed that Nike has been revisiting unfinished prototypes that were originally developed with Bryant, meaning some of those older ideas could eventually make their way into new releases.

For now, Nike hasn’t shared the name or full design of the next Kobe model. Stay tuned for more updates.
