Hello!
I need to create some kind of shoe holder to sort out the space at the bottom of our internal stairs. With two teenagers - one with a shoe obsession - things frequently get out of hand, as can be seen in the photo (there are more shoes out of the shot). On the left is the door leading to our garage; we have an over-the-door hanging shoe holder on it but the plastic pockets are flimsy, and there aren't enough of them anyway.

I'm thinking of putting up something more permanent in the narrow space to the left of the other door (see photo) , which leads outside. Its dimensions are 2400 high by 440 wide. Both of the doors open inwards so I can't have anything that sticks out much (like flat shelves). I'm thinking either shelves sloping down towards the brickwork or hooks/rods that the shoes can hang on.

Any ideas/suggestions/advice would be appreciated.
Thanks,
Mel
