There are a few ways you can store space when packing shoes. One way is to wear your heaviest shoes and put your lighter shoes in your suitcase. Another way is to pack your shoes in individual bags or boxes. This will help keep them clean and organized, and it will also prevent them from taking up too much space in your suitcase. You can also try rolling your clothes instead of folding them, which will help create more space in your suitcase for other items. Finally, make sure to pack any essential items in your carry-on bag so that you don't have to worry about them taking up space in your luggage.
