If you’re really struggling for space these back of the door shoe racks offer a possible solution. They take up little room but provide somewhere to store up to 36 pairs of shoes.
Rather than just hook over the top of the door these units fix with a metal plate and screws. Not only is this a more secure method but also means the door will close as normal.

You will find lots of alternatives on the market but steer well clear of the cheapest options as they are simply not up to the job. Bear in mind also the weight of all those shoes can be considerable. This isn’t a suitable option for lightweight or poorly fitted doors.
