Product was too narrow.  I returned it promptly.  I have been wearing reef sandals for almost 10 years and over the past 2 years their product has changed significantly in the negative direction.  I read the other reviewers who said to go a size up and I went to a size 7, I am normally a 6.  These still did not fit my feet at all.  I have a pair of these same sandals from about 5 yrs ago, they are a size 6 and they fit perfectly.  I read on other Amazon reviews that Reef has changed the manufacturer that produces these and that definitely seems to be the case as I compared these with my older pair.  I have now gone to Tevas now as they are much more comfortable and do not run narrow at all.  People do not wear the sandals if they are too narrow on your feet, you can damage your feet by doing that!
