I haven't experienced having to use such an insert but I have experienced other problems because of my OA. I have had flair ups of Bursitis in my right hip since my knees became really bad. My doctor believes this has been caused by the fact that I am walking differently and babying the left leg, where my knee is really bad. So, I guess that the way we walk in order to deal with our OA can play a part in what other problems occur in our joints. For you this could be requiring this insole, it wouldn't hurt to try it, and see if it does help.
