I have friend who be from CA and they swear by these flip flop . I wear a size 9.5 in women and so I buy the men small flip flop . the men size should have cover I up to a women size 10 accord to they size chart . I research -lrb- I think -rrb- pretty well and find they run narrow so that why I order the men - its wider . yeah , still way too narrow . its like my foot just fit in they so I can wear they but it be not the ideal situation . and I never think I really have wide foot ! my recommendation be to try they on in store if you foot be size 9 and up ! and the breaking in periood be bad too - I wear they every day for a week so I think they be good . wear they to a baseball game where I didnt do that much extra walking and I get some of the worst blister of my life on the bottom of my foot ! I limp for 3 day after my foot be in so much pain ! and yes , maybe that bc they be slightly small but still . I even research further and get they wet -lrb- people say that help stretch they out -rrb- and its STILL not great !
