The man who makes my son’s arch support just told me my son was flat-footed. My son is 11 years old. He said here in Italy they do a surgery where they insert a screw to correct the problem. I will admit now that I have looked at my son’s feet, they do look flat, but he is a sportsman, and plays tennis daily. He never complains of pain. But maybe that is because I have always purchased supports for him. What is your opinion on the surgery option?
