Tie your shoes to the front of your backpack
You often have to pack a small suitcase for outdoor activities or to sleep at a friend’s house. In those cases, some things you need to carry are too big for a backpack, such as shoes. Shoes or sneakers take up a lot of space and leave less room for other things that are also important.
Actually, as they touch the ground, they usually have germs you don’t want to be in touch with your clothes. To avoid this, what you should do is just tie your shoes to the front of the backpack, as you see in the picture. This way, you will have more space inside the bag, and the shoes will not be a nuisance.
