I know this is off topic, but consider the 5 fingers program. I know you may not be able to wear them all the time (like work) but when you do train with them they build up all those ligaments and muscles in your feet that you never knew you had and the pain goes away.

With almost 20 years of breaking myself on behalf of my government my feet, knees and back were killing me. A friend reccomended the whole barefoot running thing and I figured it couldn't hurt to try. It takes a while to get used to, but what a difference. You wouldn't believe how strong your feet will get.

After about 3 months of the barefoot running thing I am blown away with the results. Nothing hurts anymore

I am not Cody Lundine yet, but I cannot reccomend the 5 fingers enough.
