The informational book "Why the Shoe Pinches" is the sort of book you need if your feet are always hurting because of the shoes you wear. The book is a guide on how shoes should be worn and what design of shoe you need, along with the common problems resulting from flawed shoe design. Author Georg Hermann von Meyer states, "A covering for the foot has, however, to fulfil this object in a manner that will give rise to no disadvantage, the existence of which would essentially diminish the benefits of protection."
