My husband and I had three hanging shoe bags in our shared closet, taking up clothing space. I saw this shoe rack and thought it might work in the small closet space we share. It totally fit! My husband has all of his dress shoes and sneakers on his rack. On my rack, I have 7 pairs wedges on the bottom, 10 pairs of sandals on the second rack, and 6 pairs on the top rack. So depending on the type of shoe, you can fit far more than 18 pairs! Unbelievably easy to assemble, if I can figure it out, so can you! I would recommend for anyone look to maximize  space in their closet and trying to get their space organzied.
