My feet are really hurting i used to be a very good sportsmen but when i run they hurt can someone help?

You need to see a podiatrist. There are so many problems it COULD be: fallen arches, hammer toes, bone spurs, plantars facitis, ect. You need a doctor to diagnose WHICH problem it is, and then tell you how to correct it. Please, for the sake of your feet, do so. The sooner you address the problem, the easier it is to correct it.
