What happened: The WNBA posted that Caitlin Clark arrived wearing the Nike Caitlin 1, her first signature shoe. Nike has unveiled the model with an October 1 release date, giving one of the league's biggest stars her own on-court line.

Why it matters: Signature shoes remain rare in the WNBA, so Clark's launch is a major commercial marker for the league and women's basketball. It also extends Nike's investment in Clark from player exclusives and apparel into a full namesake performance shoe.

What to watch: Watch for whether Clark wears the Caitlin 1 in game action next and how Nike positions the shoe before the October launch.
