Best off the shelf orthotics I have found.
I am a physical therapist, and short of getting orthotics made for you, these are the best you can do.  Don't heat mold them until after you have worn them for a week or so; your feet get used to the support and heat molding reduces it somewhat.  If you feel that they support you too much after a week, then go for the molding.  Bonus:  they last forever.
