To supplement the orthotics, I run in motion control shoes to overcome my over-pronating style of running. If it was me, I would go see a podiatrist, get his opinion and go from there. I second the arch supports. Arch supports have not eliminated the pain, but have cut the intensity significantly. So I did a fair amount of research and tried every over the counter orthodic I could find including Hapad and Superfeet.
Some places carry fewer styles.
I use them in all my shoes. It also may be worth calling Hapad. They have an 800 number and person who answers the phone is the founder's sister who is extremely knowledgable. In my last post I explained how I am dealing with my heel spur and ankle sprain problems. Although I am running well now, my podiatrist has suggested that orthotics might be a more permanent solution over the ankle strap that I am now wearing.
