These fit perfectly and I didn't have any break-in period, sore spots or blisters. I normally wear a 9.5 (occasionally a 10 in athletic shoes) and the 9.5 fits my foot great.  One of my feet is bigger than the other but unlike with some other shoes this has been a non-issue because of the adjustable straps.  The Bungee Cord color is wear-with-everything and I've been wearing these a lot because they were immediately comfortable.  I think these will be the sandals I live in this summer!
