The Foot and Ankle, by Philip Lewin M.D. says "The training, balance, poise, muscular development, and exercise more than compensate for any harmful effects that may occur. However, they should not be engaged in too early in life, ballet. Ballet shoes and slippers may be fitted with felt paads to support the transverse and longitudinal arches and heels. In some cases the toes of the shoes should be padded." Insoles of sponge rubber are helpful. Also, request a thera band from your local sportsware store and exercise your feet, and lower extremities. Therabands help to increase flexibility at a rate you can afford to approach with confidence and little risk of harm. Diversify your curriculum and the benefits will be beyond your imagination. have fun![/i]
