I love these flip flops. I bought them to replace some very comfortable Clarks flips that are no longer made.  Anyway, I bought 3 colors.  I followed the other reviewers recommendation to order up a size and I regret it.  I normally wear 7.5 in almost all shoes.  But I have tried on Sperry shoes before and found them narrow.  So I ordered 8 in these flip flops.  They fit fine when trying them on.  However, after wearing them 1 or 2 days, the leather straps stretched and now are too loose!  One color was only available in 7.5, so I took the chance and they fit fine.  I wish I had ordered all of them in my normal size.  I am now waiting for a good deal to order the gold ones a half size smaller because they are very cute.
