For years I rode with Shimano SPD pedals and mountain bike shoes. Last year I began to develop left foot problems. I had intense pain on the outside portion of my foot near the bony portion where the phalanges and metatarsals join. I have seen a foot doctor, undergone an MRI and x-rays with no cause of the pain (at times it was too painful to bear weight).

MY DH encouraged me to switch pedals and shoes to see if that would help. I purchased a pair of Shimano 105's and a pair of Giro Factress shoes. The first couple of rides were pain free but sadly the pain is now returning about 15 miles into a ride. I have switched the arch support in my left show to shallow (green) support. That gave me some extended time today before the pain returned. I currently have the cleat centered on the shoe. Do I need to move it forward? Back? Any suggestions would be greatly appreciated.
