Platform shoes are shoes that have a big, flat bottom that raises the wearer up higher off the ground. Imagine a regular shoe like a sneaker or a sandal, but with a thick layer added to the bottom that goes all the way from the heel to the toe.
The reason why people wear platform shoes is because they can make you look taller than you really are. If you're a grown-up, you might know that sometimes people want to look taller because it makes them feel confident and powerful. Sometimes, people want to wear platform shoes just because they look cool or because they match their outfit really well.
Some people might also wear platform shoes because they want to protect their feet from getting dirty or from stepping on things like rocks or glass. The thick bottom can keep your feet safe by adding an extra layer between your foot and the ground.
There are all kinds of different platform shoes out there, from fancy high-heeled ones to casual sneakers. Some are super comfortable and easy to wear, while others might take a bit of practice to get used to. But no matter what kind of platform shoe you wear, they're all designed to help you stand taller and feel more confident in your own skin.
