My Invention
I'd like to share my invention—a pair of magical shoes.
They look just like normal shoes, but they are made of special materials. This makes them different from other shoes.With small batteries in the bottom, they can even change temperature. When the weather is cold, the shoes will heat up, keeping your feet warm like stepping on warm blankets.But if the weather is hot they will cool your feet down, like having a mini-fan inside.
These shoes are not only practical but also smart. I believe they will be highly popular among people and make our daily life more comfortable.
