I typically wear a 5.5 to a 6, sometimes a 5 just depending on the brand. I have somewhat flat feet I suppose, and believe I have a regular to overpronation. The outside arch support on this is very uncomfortable to me. The previous Skechers I have bought have not held up and lost all their cushion very quickly. But this shoe seems cushioned AND durable. And the foot bed on these particular ones seems like it might work for some people. But for me, not for the strange arch support.
