I have these slippers myself and have worn them alot in two years.  I bought a pair for a gift for my niece and she likes them alot also.  I would say they run a bit large, maybe one half size, so if you are a half size, order the smaller rather than the larger size.  The support is great and you can walk outside in the dew if you need to without getting wet feet.  These are great slippers and just like all the Fitflop products, I highly recommend them, especially if you have or have had plantars fasciitis.
