19 shoes. 19 different experiences.   It starts with one. We're not talking about the first shoe. We're talking about the one in the gym alone. The one whose soundtrack to their game doesn't come from the speakers above. It comes from a heart that's tuned to play a different chord with each dribble to the basket.   As you trace the lineage of LeBron's kicks, be sure to welcome the latest addition to the family: The LeBron XIX. A shoe made not just for the 👑, but for everyday ballers around the world. #LeaveYourMark
