The reason its called Dr.'s Foot Source, is because the doctors in the building own it. Rock River Foot and Ankle Clinic. They had to redo my shoe over, because it wasn't measured correctly. The shoe came back and now, my foot went up and down in it. One doctor tried to use pads, everywhere, but that did not solve the problem. I had walked outside on them and it voided their warranty. How can you tell on carpeting if it worked? Would it be the same walking in your garage concrete as it would outside concrete? Both are dirty. I wanted them to replace the one shoe, but, no matter what, I was denied. They can take a business loss, whereas, I cannot, because of being disabled and on a fixed income. SHAME on them for not having a heart and just want the money. I cannot walk correctly in them and it adds to my back, hip, and leg pain. It acerbates it.
