Not many people would have guessed that Mia Hamm would grow up to become one of the most famous athletes in the world. She was named for a ballerina, and born with a clubfoot, which meant she would need treatment just to be able to walk like other children. But when she was two years old, she discovered soccer in a park in Italy and never looked back. As an adult, Mia earned two Women's World Cup titles and two Olympic gold medals. Today she is retired from professional soccer, but she still loves to put on her cleats and teach kids how to play!
