I am curious as to the advice on shoes, from p146 it advises insoles and also "good shoes" with shock-absorbent sole and arch support.
My curiosity arises from thinking about what people such as the greek status shown on p147 would have worn - most likely very flat sandles surely? My personal experience with plantar fascitis was that it only went away when I got rid of my sandles with arch support and went to a much flatter model.
Information in the "bare foot running" community suggests that many problems with running come from the development of padded trainers in the 70s by Nike and others. In former times, with plimsoles and other flat shoes, there were many fewer problems.
p.s. Don't wish to seem like I am nitpicking about a book I have found very interesting and useful so far.
