In order to fix your heel pain, you need to align the bones of the foot into their natural position. You need to make them spread. Wearing shoes your whole life has caused them to be squeezed too close to each other. This position is what causes bunions, plantar fasciitis and other issues. The way you fix this problem is with toe spreading splints. I have loosened up every bone in my foot. A few of the pops when a bone loosened up were so loud you could here them in the next room with the door closed.
