McMinn’s Color Atlas of Foot and Ankle Anatomy is a very good foot anatomy for students who need more than the very basics. The book filled with images including x-rays, images of the anatomy with cadavers, and live human models. I recommend this book not only to students but to medical professionals for the clear anatomical photos that are useful with patients. I also highly recommend this book for to massage therapists, personal and athletic trainers as it helps you develop the mind’s eye view of the soft tissues and bones that you will be treating. Also available in a Kindle Edition.
