There are a few fundamental subtleties to know when selecting orthotics. The first is what material they are made of. The thickness of the material dictates its rigidity. For example, a three-eighths-inch polypropylene device is approximately 150 percent more rigid than a one-eighth-inch polypropylene device. This means that a three-eighths-foot device will be 1.53 times more rigid than a one-eightth-inch polypropylene orthotic.
Another fundamental aspect to consider when choosing an orthotic is the rigidity of the device. Rigid orthotics have very low stiffness, so they have to push up and down with 150 pounds of force in order to adjust the foot’s kinematics. This is a major consideration when considering orthotic materials, as it is crucial for the correct function of an orthotic. If the rigidity is high enough, the orthotic will be able to resist deformation and make the foot feel more comfortable.
Final Thought
There are also some other subtleties to know when selecting an orthotic. The size of the orthotic is important to consider, as it can affect the size of the shoe. A good podiatrist will be able to determine whether or not your current shoe is a good fit. They will also be able to test your feet for bend. If your feet are uncomfortable, you should go to a professional to find a better solution.
