There are three main ways to prevent the corn or callus from forming. The first is balancing with a shoe innersole called an orthotic. The second is surgery to realign the bones and provide a different skeletal structure. Third, is where a physician provides an internal cushion between the skin and the bone so that the substance placed under the corn takes the brunt of the load, not the skin. This is called cushion restoration, cushioning a callus, or fat cushion and restoration.
