Meet Luis Badillo Jr., the man who may have the world's fastest feet.

He's a Miami-based fitness trainer who trains some of the world's top athletes, including Cristiano Ronaldo. Badillo stays in shape by running drills four to five times a week, using cones, hurdles, and ladders to perfect his form. Badillo's famous footwork has made him a social media celebrity and has helped get him clients.

In other words, you wouldn't want to go up against him on the soccer field.
