Point-Counterpoint: Can Toning Shoes Have A Legitimate Impact?
5. Patient selection is essential to the success of prescribing rocker-sole shoes. Healthy, able-bodied adults, obese patients and patients experiencing plantar foot pains will benefit from the use of rocker-soled shoes. On the other hand, do not prescribe rocker-sole shoes to patients at risk for falls, patients with compromised balance and patients who are severely out of shape.6
While more studies need to occur to establish the efficacy of rocker-sole shoes on exercise, they will become a fixture of every podiatric practice simply because the aggressive advertising campaigns of the manufacturers place them front and center in the minds of almost every patient entering our offices.
Every podiatrist needs to have a basic understanding of the shoes’ effects on the human foot in order to take proper precautions and place shoes in an appropriate position in the treatment armamentarium.
