Pantofola also means "slipper." These seem to be somewhat more formal and elegant than ciabatte, and are often made of cloth and closed at the back. Pantofole are associated with the home, whereas ciabatte can be informally used outside e.g. at the beach. Pantofolaio is a homebody, someone who likes to stay at home a lot.
There is also a rather sexist proverb that says ogni scarpa diventa ciabatta, every shoe becomes a slipper. This would mean that people (I strongly suspect they mean female people only) lose their beauty and value over time.
