If you are considering custom orthotics, you should learn how a custom arch support is made. Custom arch supports help treat various biomechanical problems and relieve stress associated with arches that are too high or too low. Specifically, a custom arch support can promote correct alignment of your foot and redistribute your body's weight and reduce the impact from your foot strike. Custom arch supports will be built to your individual needs based on your size, injury, and foot strike.
The first step in making a custom arch support is for an orthopedist to evaluate you. You will talk to him to determine your reasons for seeking a custom arch support and past relevant medical history. Because the orthopedist will be making the arch support for your individual foot, they will need to conduct a thorough history of past injuries, the kinds of shoes you wear and your activity level to determine what problems you are most susceptible to and how the custom arch support will help.
Next, the orthopedist will analyze your gait. You will also be asked to walk and run on a treadmill while the orthopedist videotapes your movement. You will also be put through a series of tests to determine your strength and range of motion. Orthopedic surgeons say that this is the most important aspect in making a custom arch support because this will be the determining factor in whether your custom arch support will be full length, just along the arch, cushioning or stable.
The last strep is to take a mold of your foot to get a custom arch support. This mold will provide a blueprint of your foot so the correct modifications can be made. For example, if you have flat arches and turn your feet overpronate when you run, your arch support will probably be designed to keep your foot from collapsing inward. The materials used are usually a combination of polymer and some type of cellular cushioning.
