I was wondering if anyone here has any expirience with arch supports and/or custom orthotics. I ask this because I am beginning to get sharp pains in my feet and calf muscles when run and I start OCS on the 24 MAR. Are the store bought Dr. Scholls type inserts good or should i invest in the customs insert which are a little expensive? I realize that it depends on the person, but i just wanted to get a little outside perspective. thanks
