Stone unhappy wearing shoes onstage

English singer Joss Stone is refusing to wear shoes on stage because she feels they cripple her feet. The 20-year old Stone rarely wears shoes on stage and admits that she is too clumsy to perform in heels, contactmusic.com reported. She said: "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."
