someone in my block of flats had chucked out a set of wooden shelves. i rescued them from th ebin, and have been using them for the last 8 years now, mainly as shoe storage, but have variously used as bookshelf, and garage storage.
we currently have this bought specifically for shoe storage, (it fits perfectly) but still find we use the ole shelves....
my friend has bought some baskets from ikea with lids, and they store shoes in there. look good too..
