Throw Out Your Boxes
Sneakers don't come in cardboard boxes because they're the optimum way to store and keep sneakers forever. They come in cardboard boxes because they're cheap, recyclable, and ship easier. That box is meant to transport your shoes from the factory to the store, and that's about it. So while keeping your original shoes in the original box is the dream, it's not the best solution in reality. Face it, the only reason you need the original box is for resale — and you're not selling anything. Go to the Container Store and find a better solution.
