I doubt very much that the sore on the soles of your feet have anything to do with herpes. Please have a doctor check and tell you definitively. Your father, I believe, is not at risk from herpes from you. I have never seen herpes on the feet.
Although herpes virus can in theory be transmitted from objects in the home, in practice this is extremely rare. If you have a herpes lesion like a cold sore, you should avoid kissing anyone while it is fresh. Once it has dried up, it is very unlikely that you'll spread the virus to anyone, all the more so once it has disappeared.
I must ask how sure you are that you have herpes. In most cases, people get herpes in a single location (such as the lips.) Is it possible that you are cosnidering as herpes some sores and lesions that are really something else entirely? For your own peace of mind, you ought to check.
Best.
