One other possibility, and, yes, I know I'm a newbie, is that you may have developed plantar warts. I had these when I was younger and marching/running long distances. Took forever to get rid of the little buggers and they caused pretty much the same symptoms you described. They did not start burning/hurting until after I had stood for over an hour or marched/run for at least that long.
If you try what everyone else here has suggested and still have the problem, then have a podiatrist check the soles of your feet for plantar warts.
