My cool invention
Many of us may have to throw away our shoes when they are too small for our feet. It 39; s a big waste. And sometimes new shoes can be too tight for us to wear.
This will not be a problem if you wear my Cool Shoes. The shoes are made of special materials, which can grow with your feet and always fit your feet. What 39; s more, you don 39; t need to worry about wearing too small or too big shoes anymore.
The shoes don 39; t cost much. So just have a try!
