Four-year-old twins Jimmy and Janet cannot wait to grow up, and they are especially eager for their feet to grow so they can get brand new shoes. They head to the shoe store with their mother, hoping to buy shiny new pairs just like the big kids wear. However, the shoe salesman measures their feet and delivers some disappointing news: their feet have not grown enough for new shoes yet. To cheer them up, their mother buys them each a pair of bright red rain boots instead. The twins are absolutely thrilled and immediately want to splash in puddles, but there is one major problem. There is not a single rain cloud in the sky. This charming and funny story captures the impatience of waiting to grow up and the simple joy of splashing around in new boots. It is a perfect slice-of-life adventure for young readers eager for their own growing-up moments.
