I have just found out I have flat feet and I have just applied to join the Royal Navy. My feet have never caused me any problems and I have never worn any special insoles. I have never visited the doctor in relation to my flat feet which were diagnosed in a school medical when I was 6. My parents never mentioned it as it has never been an issue. I know this question has been asked before but other people have had pain or orthopaedic insoles. As I have to fly to the UK for my medical, I would really appreciate any information anyone can give me. I have no problem running or walking.
