As simple as it looks, orthotics are the most advanced and effective external prescription available for general foot pain. They do not merely serve as arch supports but also control the way your feet function. In addition, orthotics act on bone structure, forcing the feet and legs into their proper alignment.
Orthotics will not change the underlying structure of the adult foot, but may prevent the development of pain and disability such as back and neck pain, and the development of additional deformities such as flat feet, bunion, corns and calluses. However, if they are not worn, abnormal function will immediately return and this is the main reason why orthotics need to be replaced.
