I think they look better off, and provides a bit more clearance, but like other posters have said, they help protect against gravel and rocks from chipping the paint on the doors and rocker panels. It's unfortunate the way they are designed though...too narrow to act as a real step for an adult, and for those of who don't need a step to get out, it means you have swing your leg out farther so that you don't bang your calf on it and get salt and dirt on your pant leg.
