I wear Saucony to run, Id been fitted w Omni 13 at running store where i ran on a treadmill while my feet were videod to show I could wear either a stability or neutral shoe.  I chose stability, they felt a little better (wore neutral Saucony grids prior).  Thought this purchase of Omni 15s at a great price  was a no brainer.  Put them on they were comfy!  tried to run (treadmill) and was in pain almost instantly. Shin splints, sore balls of foot, not what I would have anticipated, ever, from this brand.  Put my old pair back on and finished work out in those (pain free). Then home to scratch my head and examine new shoes.  Compared with Omni 13 these shoes appear to have gone further with the stability into zone of correction, pic of back of both shoes shows what appears to be increased angle of stability shoe).  Hurts!  Am returning these.  Switching back to Saucony neutral shoes.  Two stars due to brand loyalty.
