A custom orthotic is a device designed to align the foot and ankle into the most anatomically efficient position. They look like insoles but are biomechanical medical appliances that are custom-made to correct your specific foot imbalance. Custom orthotics work on your feet much like glasses work on your eyes – they reduce stress and strain on your body by bringing your feet back into proper alignment. The plastic body of the custom orthotic helps to re-align the foot by redirecting and reducing certain motion that takes place during the gait cycle. Custom orthotics fit into your shoes as comfortably as an insole – and they have the advantage of having been made from precise imprints of your feet.
