People are always looking for storage ideas. Anything that would hold shoes could be used for other storage in the garage or base of a closet or entry way hall. I would use it for crafts, my hubby for tools, and kids for Music or game storage. It depends on the shape and build of the shoe racks. Some are like wires and hold individual shoes while others are like tilted shelves. Georgia, you might sell it in a yard sale of you do not find a use for it, or donate it to a charity.
Depending on the size of the shoe racks you can use them in your kitchen cabinets or pantry to give yourself more storage. I have some in my lower cabinets and they double my storage and I am able to organize much better.
How about plant holders for pots or plant trays
I used a shoe rack for craft supplies!
