easy………right on top of one another.   We decided to use a camera for good rather than evil today and stacked up 9 boxes in the middle of the bedroom in order to give you an idea of how to stack and How Not To stack the boxes. 

How to stack Shoe Stör’s clear boxes

Well, first of all, don’t stack them 9 tall in the middle of a room;

When you removed a pair of shoes from a box, close the clasp.

Notice in the first picture, we have an empty box near the bottom.  When you have removed a pair of shoes from a box, be sure to close the box when you remove the shoes.  Leaving the box open decreases the structural strength of the box and leaves the possiblity of a box collapse.  Not much of an issue if you have a stack of 2 or 3 boxes, but if you are a “closet “daredevil and think that a stack of 12 or 13 boxes is a neat thing to show your friends, make sure you close your boxes

How not to stack our clear boxes

This second picture demonstrates how not to stack the boxes………..with an open box somewhere in the middle of the stack.

As far as how many boxes to stack on top of one another.  It is really up to your descretion, but remember, at some point, the laws of physics do apply.
