When you take the insole out of your shoe and replace it with an insole that is custom designed for your foot, the insole is now called an orthotic. Orthotics are used to improve your foot function, and when your “foundation” is working better, the rest of your body can work better. Your feet affect your knees and your knees affect your hips and low back, so sometimes you need to fix your feet in order to fix your back. We use “Footmax” orthotics; we like them because of how they analyze your foot. In the old days, you either had a plaster cast made of your foot while you were sitting in a chair or stood in a box of foam that compressed under your body weight. Footmax has you walk across a force plate that captures an electronic picture of your foot as you walk. The orthotic is then made to bring your foot function as close to ideal as possible. If you have particular foot problems (like plantar fascitis or a Morton’s neuroma) the orthotic can be modified for the specific issue. Footmax is a “semi-rigid” orthotic which means it is more comfortable to wear than the really hard plastic ones. They last a long time, my original pair is three years old and has held up well. Both Dr. Susan and I use them in our running and walking shoes.
