I did read other reviews before buying.  I went ahead an ordered a size up and glad I did. So I checked size to fit as expected because I ordered up. The front part of the sandal is a bit narrow but fits my foot fine (I can sometimes wear a narrow in a shoe with a wider toe box area).  This sandal looks great and is very comfortable. The arch support is just enough.  I have worn them all day without a problem. Because of the cork bed I expect them to get more and more comfortable.  Glad I bought it.
