I am seventy years old, 65 in height, and weigh 195 pounds. I have pain in the tops of my feet, and the tops of my feet look a little distorted in height. I have high arches. I think the pain is related to my being overweight. When I have been sitting for a long time and get up, I limp because of the pain. But after walking maybe 30 steps, the pain goes away, and I can walk briskly without limping. But when I am site-seeing with my family for hours, my feet become achey. They aren t sharply painful, but feel tired and achey, and I want to sit down. Advice?
