      Sometimes we may find our favourite shoes are too tight for us to wear as our feet are growing. So we have to throw them away. Then they become a big waste and may pollute 
the environment. However, with my new invention--Cool Shoes, these will not be problems any more.
      The shoes are made of special materials. They can become big or small according to the sizes of your feet. What's more, the materials of the shoes can be recycled. When you wear my Cool Shoes, you are also helping protect the environment. So just have a try!
