A good pair of shoes is (almost) essential to exist in this modern world as a Human.  Ensure they fit right, make sure they're good quality and well built. And make sure you know what you want to do in them and where you want to go. They will literally be the things that get you to so many places in life that you wouldn't be able to get to otherwise. If you want to strike a pose at the end of a catwalk, or climb to the top of a mountain, feel good sitting down, run fast or stand still, dance or dive, go to school or go into battle... make sure you get yourself a good pair of shoes.
