I have extremely flat feet so it is quite difficult for me to find comfortable sandals and I have been able to do just that in these sandals.  The colors of them are great and bright (I got the Purple/White and LOVE THEM!) and I couldn't be more pleased with the selection.  I got them for a steal of a price, extremely quick shipping (way to go Amazon!!) and just couldn't be happier with this order.  They didn't have my size in stock (10) so I ordered an 11 and they actually fit me perfectly so I have found that they run a little smaller than at least Nike's, but I thought I remembered that being the case in the past so I was glad I ordered a size bigger!  I have relatively narrow feet and do find that these sandals are slightly snug so they are definately not for anybody who needs a wide shoe.  As I said before, I couldn't be more pleased with this purchase and if given the chance again, I'd purchase them all over, exactly the same!
