Dear Lady,
Ask your doctor to refer you to a certified pedorthist (a C.Ped.). They are the folks who adapt, design, build, or modify foot wear.
If you have trouble locating one, let me know. I'm an MD who is on the board of their national organization and can find one for you.

What I tell you is what I teach. I'm here to help improve your quality of life, and I'll work with you as long as necessary to help you.
