this be a gift for my boyfriend , I originally buy a pair of these sandal at a store in Vegas but the cork on the sole split and break very quickly -lrb- these shoe be suppose to last a long time -rrb- . then I notice that there be two version of the same shoe , a cheaper one make of synthetic material and the original one , in leather . I find the stronger original one here on amazon for 71 whereas the one I get at a mall in Vegas cost 89 + tax . I receive they quickly and they be perfect ! thanks !
