Connie you stated you have planter faciitis, correct ? if so one of my sister's also had that and her doctor told her to wear a good pair of shoes with a good arch at all times except of course when she went to bed. He said that the way to get rid of the pain is to realign her foot and it worked for her. He also said that even though foam makes your foot feel better, it actually makes the planter faciitis worse.

Here's a wensite that explains what it is and how to get rid of it.
