thanks for the advice-- I actually just bought these shoes from a very reputable running store. They did look at my arch before helping me choose, but maybe I should head back to them and see if maybe they have a second recommendation. It would be nice if that was it-- another pair of $80 shoes-- since the PT was much more expensive (and not entirely paid by my insurance-- had to pay $15 copay for every visit!!) Thanks again for your help!!
