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.
About Toning Shoes:
Toning shoes are casual shoes that feature a recently developed thick and curvy sole designed to increase muscle activity in the legs as well as to shape and tighten the lower body muscles. Toning shoes create a rocking imbalance, some shoemakers claim, that can reduce back pain and enhance muscular toning when walking.
