I quote from page 22: "Abnormal supination will receive short shrift in this book, as it accounts for only a small percentage of all the foot problems I have seen in my years as a podiatrist." As a larger framed supinator who started actively running last year, getting the proper shoes and orthotics for my feet have been quite a chore. I tend to callus heavily on my fifth metatarsal, and have to use a callus shaver twice a week on them or else they become so thick and painful that I have difficulty even walking. I am using neutral plus running shoes, Dr. Scholls orthotics along with memory foam, with partial-at-best results. I have seen two local podiatrists who were completely useless at helping me. One of them advised me to stop running and switch to yoga. Glenn Copeland seems cut from the same useful cloth, as he then devotes one or two paragraphs to the idea that I would need custom orthotics, which I have been unable to obtain. And, the ones that are available by mail order, he says, are only partially useful, at best. I already knew that. There was a small amount of helpful info in the book, but nothing I didn't know already. I knew I had a problem being a supinator and that my 5th metatarsal calluses, and that I need something in my shoe to prevent it, but not how to find it (especially when the only doctors my insurance pays for turn out to be completely useless). I read this book, and now know exactly what I did before reading. I don't know anything about how to improve my current situation. If you are a supinator, or have a problem that would require orthotics for your 5th metatarsal, you will not find any information in this book to help you. The author says so himself, on page 22.
