Well, let me say that it is ok for storing shoes and being able to visibly see them.  I have looked for a shoe storage unit for years and I thought I had found the one I wanted.  Flat shoes fit into the slots well enough but not wedges or heels.  I wound up putting these kind of shoes in just one slot each.  They fit that way, but it makes for less number of shoes you can store.  I am concerned about the slots being left open.  Dust can get inside.  I would have preferred it to close up tight.  For the price paid, it is an ok storage unit.
