I said these shoes fit as expected because I have worn FitFlops Sneakers before and know how their sizes run. If you are unsure, find all the reviews of FitFlops on Amazon and read them all. There is a ton of information about fitting these shoes, which are spectacularly comfortable for someone with my foot problems. I don't wear any other shoes when I am going to be walking a lot. The thickness and softness of the sole are what makes them so great for me. The soles are soft but not all air, like memory foam which squshes to no cushioning when you put your weight on it. These are a substantial soft.
