I've gotten my custom orthotics and put them into my running, tennis and bike shoes, and all I can say is wow! What a difference they make. I still have some leg and back pain with biking, particularly on longer rides, but it is more manageable with the shoe inserts. Correcting the positioning/pronation of my feet seems to help all the way up through the knee, hip and even into my back. The doctors and therapists have told me that it will take time for my skeletal structure and muscles to adapt to the correction provided by the inserts, since they are readjusting the mechanics of my body. But hopefully the orthotics, in combination with the stretching and strengthening program I'm currently on will provide the mechanical correction necessary for restoration of my joint function and gradually increasing pain relief. At any rate, I can now ride my bike for nearly an hour at a time, play tennis through a full match, even run - albeit slowly - for a couple of miles . I don't do all these things in the same day of course, but the new footbeds do expand my capability for avoiding burnout and boredom, not to mention aiding my exercise capacity, by giving me the opportunity to participate in a variety of activities with increased comfort and stability.
