I have Fitflop sandals in numerous colors, clogs, and lounge slippers and they are equally well designed.  However, I was a tad bit disappointed with the sneakers.  Since I have resorted to all Fitflop shoewear due to plantar fasciitis problems in the past, I need that arch support that is a part of all their other shoes.  The arch support in the sneakers is just not there at this point.  The soles of the shoes are extremely firmly cushy for a very comfortable feel when standing, but I miss the higher arch support.  It might be that the shoe will mold to my foot over time, as I've had them only about a month or so and have worn them only a few times.  I love the style and the thickly cushioned insole.  I have a large foot: Ladies 11 Wide.  Normally, the fitflops are plenty wide in their normal medium width and in fact I can sometimes wear a size smaller.  In the sneakers, I had to put shoe stretchers in the toe box end to give me more room.  If your foot isn't wide, that wouldn't be a problem.  I bought a size 11 and needed every bit of it.  They probably run true to the size you normally wear, but narrower than most Fitflops.
