The Foot Book is one of Dr. Seuss' most unique and interesting books in the sense that it lacks a more traditional narrative. Through rhyme, repetition, and the depiction of a number of different kinds of feet ("Wet foot, dry foot. Low foot, high foot..."), Seuss wanted to show young readers that there are opposite things in the world. He also wanted to encourage younger readers to pick up a book and read. As well as that, he wanted to encourage younger people to be more accepting of the differences with people - no matter how big or small.
When it was released, The Foot Book received positive review. Common Sense Media, for example, loved the book and wrote that Seuss, who is "Teaching through disarmament is a Seuss specialty, and it's on full display in this fun book." Former President Barack Obama also loves the book and said that “Pretty much all the stuff you need to know is in Dr. Seuss.” While not one of his classic books, The Foot Book is certainly a solid addition to Dr. Seuss' bibliography.
