SEE SPRING Shoe Storage Organizers Box for Entryway Clear Plastic Stackable Sneaker Container Bin Holder,Set of 12,White

Straightforward easy assembly even had there not been any instructions. Good for shoes not much taller than 4” total ie the entire shoe not just the heel height. Strappy sandals with a 4” heel fit fine though. Otherwise, just lay the pair of shoes on their side jut like you get them in the box at the store. The plastic frames around front and back of the shoe box gives the entire box ample stability and they lock and stack nicely. Ventilated back is a nice touch; the pull handle on door is convenient. The plastic encasing is not a strong or firm plastic so, if you have heavy shoes (like a couple of my wooden 4” heeled shoes) I'd put them at the bottom though you have a little more support with two layers of plastic sheeting. Great for sandals and tennie shoes. What a great way to store all your shoes. Only regret was ordering only 2 sets but that is easily remedied :-).
