Every time Ja steps on the court, it's showtime. To help him elevate his game, we worked with him to make the bounciest JA signature shoe so far. The JA 3 is light, tough and a game-changer with full-length Hybrid ZoomX foam. "ZoomX is crazy responsive", Ja says. "I call it that jet fuel". We call it bad news for his defenders. With its extra-durable rubber outsole, this version gives you traction for outdoor courts.
