For me, it was a physical therapist (I've added my story as a sibling comment to yours.) That was the first professional I saw that watched me run and evaluated all parts of my body. The shoe stores and podiatrist only looked to see if I was pronating and at my feet. The chiropractor only looked at my back. The orthopedist only wanted to look at an MRI or bone scan. A massage therapist who works with athletes and/or is/was a runner may also be able to help. But honestly, I'm sold on the value of a good PT.
