I've had this same problem for years and went thru all the same B.S. as everyone else, the shots, night braces, heel inserts, celebrex, etc. I have never spoken with anyone who has been helped by these methods, it's amazing these "solutions" are still prescribed. A few years ago I needed a pair of sandals quick so I bought a cheap pair, and I mean cheap in price and quality . The heel area quickly collapsed causing more support to the arch area, my feet never felt better. I now purchase standard inserts with arch support (something the heel inserts from the doctor didn't have) from drug stores for all my shoes and the problem has mostly disappeared. Other people with this problem have told me they had to go with custom inserts but the bottom line is inserts seem to work for most individuals. Had the doctor suggested trying these simple methods first it would have saved me some pain and the insurance company a good bit of money. Good luck to you.
have a line of shoes/clogs/sandals for high arches. In your search for the shoe that you can easily slide on and off (to let you maintain the barefoot feel you love), unfortunately form must always come before fashion...and, failing to find some retail product, you may have to go for custom-made shoes (again, go with a clog/sandal you can slip on and off) which can go for several hundred smackers. If you do this, make sure they have a very, very good return policy if you're not completely satisfied.
Shelly--this just gave me cold chills. Needle. Heel. Needle going into heel. 

Oh, a fat frump, according to Mr. Trespasser.
