Kelly is a dancer who is having a really hard time practicing on her broken leg. Her good heel is off balance with her flat cast boot which has a rubber sole and creates too much traction on the wood floor while her one good shoe glides effortlessly on it. The result is a bad foot ache an toe cramps which she needs to massage. Finally she can't stand it and takes both her good shoe and cast boot off to give herself both balance and and the ability to better slide on the floor.
