I love these sandal . I wear mine all the time , so I order some for my boyfriend . I think that they would fit because he wear a 9.5 and I order he a men ' medium -lrb- 9.5-10 .5 -rrb- , but they be too small . the shoe last forever and form to you foot , so I definitely recommend they , but I would suggest go up a size if you be order online and can not try they on .
