I recommend the following brands of shoes. They generally have better than average arch support and many of them have a remove-able liner, allowing you to use your own orthotic or arch support. Have your foot measured while you are standing. Determine both the length and the width. Then, use that information as a guide to try on shoes. You may very well find that a shoe an entire size larger is the most comfortable.
