Custom orthotics are devices that are designed to better align the foot and ankle in order to boost their efficiency and function. These devices look like insoles only that they are custom made to suit your feet. The purpose of these devices is to help enhance alignment of your feet. By realigning the foot and ankle, custom made orthotics can really help to get rid of strain and stress throughout the body. The orthotics, once customized for your foot, can fit perfectly just like the ordinary insoles. You will have to provide an accurate imprint of your feet in order to have the orthotics customized for you.
