Abstract
Systems and methods for toning footwear include a combination of a support ring, an insole with a cushioning material configured to contact a user's foot, and an outsole with one or more convex regions to create instability in the footwear. The support ring or stiffener band can be coupled to the outsole between the insole on one side and the forefoot and heel toning convexities on the other side. In some embodiments, the stiffener band can be formed of a material different from and stiffer than the material of the outsole. In accordance with various embodiments, when a user wears the toning footwear while walking, an increase in both the toning and strengthening of the calves, hamstrings and/or glutes results.
