I've got an enormous accessory navicular on both feet (blew the LHS guys mind when he punched out my supremes), and while these molded to my foot ridiculously well, they're causing a good amount of pain after about half an hour. It happens a lot quicker if I have to walk in them. Does anyone know if you can stand in these during baking, or would I just be better off hitting them with the heat gun more? The damn bone sticks out further than my ankles! Other than that, these things are great.
