These sandals are very comfortable right away- no break-in time needed. The sole feels well cushioned and the upper is very soft on the inside.  The length was perfect for my average size 10 feet.  I like the style of these over most other Fitflop sandals, I think it looks more like a regular sandal (it's not obviously a "toning" sandal).  I bought these in black and they look stylish.  Very happy with choice.
