I need shoes and boots with a good arch support. I've got flat feet, and when I first went into the service, the boots I was issued had no arch support in them. After about 4 days, I couldn't walk because my feet hurt so bad. I was sent to the clinic, and the M.D. gave me two pairs of arch supports to put into the boots, and it was like a miracle! The pain disappeared immediately! I now wear orthotic inserts in all my footwear. They're great.
