We opted to hang over the door and are amazed at how well the rack sits and holds solidly without movement, which is something we thought about as the door is opened and closed.  Shoes fit nicely on the racks and are secure - again because of the opening/closing of the door I was concerned. I prefer to have my shoes up in my direct line of vision than on the floor.  Some of the floor shoe racks I have used in the past were wobbly or dust collectors.  The only 'shoes' that didn't fit on the rack were my cowboy boots and my snow boots.  But they aren't shoes.  I would recommend these to anyone who is thinking about purchasing them.
