BTW, I remember reading an article (not in RW) about the Army testing the effectiveness of insoles. They had 3 groups: a. guys running in boots with insoles, b. without insoles, c. running in boots without insoles but who thought they did have insoles. Groups a and c reported the same amounts of injury and pain over a period of time, but much less than those reported by group b. I don't know where I read this (I think it was an outdoor gear website) or how true it is, but interesting if true to see how strong the psychological factor is.
