I think even a person with medium width feet would find them tight. They are VERY comfortable and this is by far the best attributes they have. I have worn Hurley One and Only Flip Flops for many years and these ones are not the same. Well made, nice finish, reasonably sturdy, easy to assemble. I am a size 8 usually so I ordered a size 9. After reading reviews, looking through pictures I decided on these sandals given they looked pretty well put together and had a very highly padded heel which I find to be a requirement when sometimes I wear the sandal for the upwards of 8-10 hours in a day. They fit about the way a 7 1/2 M would fit me. Tal y como indica descripción However, despite coming apart easily, they did all work when the package was opened and still work despite being very unpleasant to wear without the rubber pieces. Me quedaron muy bien, son confortables pero la suela no me gusto pues por el tipo de material es muy ruidosa especialmente si me levanto durante la noche.
