other than one of those mesh shoe holders which I have tried. And Im not a shoe box fan either living in an old 1940s home space is limited--open to ideas from anyone!
One of my friends uses one of the rolling rectangular plastic storage bins to store her shoes under the bed.
How many shoes do you have? I had redone my hubster and mine bedroom, and I use my old dresser to hold my shoes. We got rid of the dresser that was big and useless and started using plastic bins instead so I had my grandmother's dresser available. Have you thought of building like a tower of shelves in a corner to stack/place your shoes?
I met a girl who had hide away bed and instead of extra mattress she used for her shoes!
