Not all NBA players with sneaker deals have signature shoes. Signatures like Jordan shoes are created in collaboration with (or sometimes designed by) a particular athlete. The shoe will carry the athlete's name and its features will connect to the player's personality and style.
Some players sign signature shoe deals. Others get player exclusives — an existing shoe customized for a particular player.
For example, WNBA superstar Caitlin Clark has signed with Nike for a signature shoe line. But she has also been using and promoting player-exclusive Kobe sneakers.
Players can also get player-exclusive versions of their own signature shoes. For example, A'ja Wilson recently showcased an unreleased pair of "Peach Jam" A'Ones, assumed to be her own player-exclusive colorway of her signature shoe.
On the other hand, a star like James Harden represents the quintessential signature athlete, having a long-running partnership with Adidas that has resulted in a deep line of shoes, such as the Harden Vol. 9. These sneakers are explicitly designed to support his unique, explosive style of play, featuring custom cushioning and traction patterns tailored for his famous step-back move.
How many players in the NBA have a sneaker deal? Currently, around 30 NBA players have signature shoe deals. You'll see several more with player exclusives, or even NBA players with Chinese sneaker deals and other arrangements to promote shoes in international markets.
