Soul singer Joss Stone refuses to wear shoes onstage - because they cripple her feet. The 20-year-old is rarely seen onstage wearing shoes during performances - and admits it's because she is too clumsy to perform in heels. She says, "It's nothing to do with being grounded and it's nothing to do with a statement. I just don't want to fall over. I love shoes and I think they're sexy and gorgeous, but they hurt and you fall over a lot. "I'm totally clumsy, especially when I'm on stage because you gotta get into it and sometimes your whole body is involved so you can't trust yourself to stay standing."
