These are great. They’re a little flimsy but once you stack them, they’re pretty sturdy. I was able to fit 3 to 4 pairs of summer flat sandals in one, 2 pairs of tennis shoes in one, 2 pairs of crocs in one, 2 pairs of heels or dress shoes in one, and only 1 pair of boots in one. But the result was pretty nice. If you purchase these, read the directions carefully, there is a small plastic flap on each end of the folded box that you have to fold over (4 total on each box). Also, make sure you put the end caps on so the indentations where they fit together with the other boxes are the same(indented on one side, protrusion on the other). Very easy.
