I have 6 or 7 pairs of fitflop sandals; I love them and almost wear nothing else in the summer!  I haven't worn these for a long period of time yet, so I can't attest to the logterm comfort of this particular style.  But in general, fitflop sandals are the most comfortable shoes I own, and I kind of have a shoe problem and have ALOT of shoes! But very importantly, I read reviews on other websites before ordering these, and they said the fiorell runs smaller than the othe fitflops.  I wear a 7 shoe on average, but every pair of my fitflops are a size 6.  I took the reviewers' advice and oerdered a 7, and am glad I did.  The 7's fit perfectly, and I am sure that the 6's sould have been too small.  I hope this helps!  Otherwise they are very cute! the only drawback for me is that the studs on the flowers are a brassy color, and I would have preferred a silver or even antique gold.  I thought the brass color looked kind of cheap.  But that's my personal preference, and didn't bother me enough to make my rating less than 5 stars!
