1) Where good and supportive footwear. I personally find that the only footwear that I can walk in easily and comfortably is some running trainers. Running trainers do have some disadvantages though especially if you are living in the UK in the winter, these are that they are normally not water proof and they are normally designed to let the heat out and not keep it in. Still for me they are well worth the compromise.
2) Can't say that this is the best advice but it has helped me, it is actually something that I don't do consciously and would not recommend it. I actually tend to walk on the outside of my foot. Not sure how easy it is to tell from the picture below (actually taken when I was sitting but tried to get a representative image) but that is kind of how I walk. The running trainers are what make this possible without snapping my ankle.

5) Take the weight you do have off of your feet - I have found that sitting down as much as possible has really helped with the pain, sure it is not a solution to your problems but it does help the pain go away until you next get to see the foot specialist.
