One of the most famous cleat artists in the world says he's lucky to be alive after a bad car crash in Miami this week ... and his ultra-famous clients are offering their support.
"SolesBySir" -- real name Marcus Rivero -- has designed cleats for superstars like DeSean Jackson, Terrell Suggs, Reggie Bush, Marshawn Lynch and more for year ... and is widely regarded as one of the best in the business.
But tragedy struck Thursday in Miami when his vehicle collided with another car, forcing his Mercedes-Benz to veer off the road and slam into a tree.
