hello all ! I receive my birkenstock as a graduation present when I graduate high school back in 2003 . Ladies and Gentlemen , these be remarkable sandal . amazingly , they be still hold up ! they do show sign of wear e.g. some of the cork be look old and crackly , but they still feel wonderful on my foot . I suspect I 'll still get another few year out of they . note that I mostly wear these on vacation and weekend . I have read other review about how the leather upper can cut into you foot . this happen to I the first week or so that I have the sandal . the person and the Birkenstock store alert I to this , tell I that they need some breaking in time . she also mention that it could give you blister while the leather soften . just be patient guy . like every good leather shoe , this one need time to break in . give it some time and the sandal will last you for year . . decade in my case !
