These shoes are great for running. I have flat feet, and the arch support is great. However, the toe box is too small. My pinky toe has ample room, however my big toe is squished against the inside and after a workout, my big toe does hurt a bit. I was hoping that the shoes would stretch out a bit after a few uses, but the tight toe area is still an issue. I would only recommend this shoe if you have a very short big toe.
