Orthotic insoles are devices placed inside the shoes with the purpose of restoring natural foot function. This is necessary when the natural biomechanical balance of our lower body has been disrupted by altered foot mechanics and malalignment. Many common complaints such as heel pain, calf pain, knee pain and lower back pain are caused by poor foot biomechanics. Orthotic insoles realign the foot and ankle to their neutral position, restoring natural foot function. A wide range of orthotics are available for different foot problems.
