About Rocker Bottom:
Rocker bottom shoes are shoes that have a bottom that simulates a rocking motion when the person stands or walks in them. The soles on rocker bottom shoes are thick and curved, which cause rolling movements that simulates walking and standing on uneven ground and forces the body to make compensatory movements. These movements tone leg muscles and help relieve pain associated with a variety of foot problems. Rocker bottom shoes may also be called toning shoes.
