I am surprised that wearing orthotic inserts in your shoes has not been mentioned. Years ago you had to get them custom made and they cost a lot - not always covered by insurance. Now, however, the foot doctor's office has premade orthotics that are specific to your foot problem. There are also different types for different shoes - I have two kinds, a larger one for athletic shoes, and a smaller version for dressier shoes. They only cost about $50 per pair, and for me are more than worth the investment.
