When storing the shoes never let them touch each other! Or else may scratch or worse plastic stick to each other.
This is very true, all of my friend's Chanel shoes got stuck together after she stored them touching each other. After pulling apart, the top layer essentially peeled away. Ouch.
I haven't had this happen with any of my full grain shoes thankfully. Only the top grain / binder stuff.
Keep them in the box separated by the paper or in the provided (separate) shoe bags
