From my own experience (Nike frees) the load I exert in the strIke is noticeable lower (but then I have lost 9kg since starting using them), and at first I noticed that my calf and Achilles shortened they have now lengthened to levels far greater than prioto switching to a fore/mid foot specific shoe.
My only real complaint is the usual one with nike products the quality is seriously lacking, in less than 200 miles I have worn a serious amount of the rubber on the sole away, I don't think their quality is what it should be.
