I own a pair of these back when I be in high school and I love they so much I wear they down to the cork and then some . recently my boyfriend mention that he want to purchase a pair because he try on he brother 's birk and find they to be really comfortable . we both order a pair online and we love they so much that we even where they inside the house . accord to the Birkenstock website , narrow be a north american equivalent of normal so if you width be normal order the narrow . the size be true to size so you can not go wrong order online . if you be unsure of which size to order , order the smaller one . I be usually a size 7.5-8 and I order the 7-7 .5 size -lrb- 38 -rrb- . the soft footbed be great for I since I have flat foot and now I wonder why it take I over 10 year to replace my first pair . this be one purchase that you will appreciate and enjoy all summer long .
