The book is a useful tool in both reflexology and holistic therapy. It helps give an understanding of the person you are treating by the appearance and behaviour of their feet, it unlocks the the hidden codes and subtle body language that the feet use.
It does not provide a foot map like traditional reflexology books, rather explains the meanings behind characteristics of the feet, for instance markings on the soles of the feet, the relationships between toes, and colour changes.
I'm glad I bought this book, and have even bought it for other people too!
