Orthotics, also known as orthoses, refers to any device inserted into a shoe, ranging from felt pads to custom-made shoe inserts that correct an abnormal or irregular, walking pattern. Sometimes called arch supports, orthotics allow people to stand, walk, and run more efficiently and comfortably. While over-the-counter orthotics are available and may help people with mild symptoms, they normally cannot correct the wide range of symptoms that prescription foot orthoses can since they are not custom-made to fit an individual's unique foot structure.
