I have run in these for years, and I LOVE the new model, the smaller heel to toe drop is just what I need with longer distances, and the fit - Saucony seems to have the women's, at least this women's, fit just perfect.  Can't comment if you are switching brands, but I like these better than the last several years worth of Triumphs, just for the lower heel. Fit is the same, which is right on for me.
