before I begin , let I say that before I pull the trigger on these I be very skeptical about pay $ 45 -lrb- the price when I buy mine -rrb- for a pair of flip flop . I be guess that if you be comb through review , you may be feel the same way . here be what I have find after pay the $ 45 : Bad : as many other review have note , there be a break-in time for these sandal , which be about 1-2 week depend upon how long you wear the sandal per day . I have pretty wide foot and the strap be tight across the top and both side of my foot , but it never cause blistering or anything worse than the feeling of the strap be too tight . also realize that any flip flop that be better quality than the Old Navy plastic one will have this period of break-in , with possibly the exception of Sanuks . I have previously own reef smoothy sandal and leather smoothy sandal and both pair have a similar time of break-in . good : I have be completely satisfy with these sandal , and they be worth the price . as state above , I have previously own 2 pair of reef , which be both slightly cheaper than the Rainbows . the first one be a smoothy sandal which be nice , for a while . I have very sweaty foot and my sweat would cause a black foamy substance -lrb- from contact with the smoothy plantar surface -rrb- to form between my fourth and pinky toe . I have no idea why this happen . they also wreak after about 6 month . I discover , however , that leather surface do not produce the smell nor do they hold sweat so I decide my next pair would be leather , again reef . that pair be about $ 5 less than Rainbows , but they be complete trash . in about 3 month the leather from the plantar surface of the sandal begin pull away from the sole of the flip flop . it look horrible and the separation become so bad that the sole of the sandal would hang down and catch curb or stair . so I toss they and purchase these . I have have these rainbow for about 2 year . they literally look just as good as the day i get they , except that they be wider now -lrb- from break they in -rrb- and there have be some wear away of the tread on the sole of the sandal . there be no separation of the leather from the sole , even after get they wet several time . the arch support be great and have not fall . I love these flip flop and I wish I have save my money and purchase these the first time . if you be debate between high quality flip flop , especially if you be look at reef , please purchase these . the quality of the Reefs have plummet , but these seem quite reliable .
