I had a real issue problem because my sciatic nerve back harniated to my leg and cause me plantar facilities . And i couldnt walk because of it.
When i buy new shoes it didnt hurt but after two monthes its start again so i needed to buy new shoes almost every 6 monthes. I didnt know how to underatand whats happening and doctors didnt tell me any thing to understand the mechanism , the root so i just suffered silnly until i decide to grasp my self and start my own investigation at nights
