I have three of these in my closet - two for shoes and another for miscellaneous accessories. They are invaluable for organizing! As for fitting shoes in them, bulkier shoes such as running shoes, high heels, etc. need a cube for each shoe. Smaller shoes such as sandals, flip flops, etc. can easily fit as a pair into one cube. My size 8 shoes fit all the way in with about 2 inches of extra depth. The other one easily holds rolled belts, wallets, small clutches, scarves, gloves, etc. I often forget about accessories that I can't see, so the open cubes ensure that I will see (and therefore wear/use) more of my accessories. These are probably the most important organizing tools that I have in my closet. I've been using them for over a year and they are holding up wonderfully!
