Abstract
Several embodiments of a therapeutic rocking shoe, provide for the fore and aft reversibility of the shoe relative to the wearer's foot for working different muscle groups of the lower body. Each embodiment has a flat upper or insole surface, with a convex asymmetrically longitudinally curved sole or lower surface. The sole has a greater degree of curvature, i. e., a smaller radius of curvature, at one end than at the other, with the central portion of the sole having an intermediate degree of curvature. This varying curvature produces different effects as a wearer of the shoes rocks forwardly and rearwardly on the shoes, thus exercising various muscle groups in the lower body. The present rocking shoes are easily reversed relative to their longitudinal orientation for the wearer to place either the greater curvature or the lesser curvature of the soles generally beneath the heels of the wearer, as desired.
