I had purchased a pair of Curves fitness sandals which I found extremely comfortable but they only came in one color, so I decided to try the FitFlops in bronze. They are cute, but they are not comfortable. I have tried several times to wear them and break them in and toughen up my toes, but it is unbearable--they rub me raw within minutes. Also, where the sole of the Curves was very soft and comfortable, these are rock hard. Personally I don't think either of them do any toning. Try Skechers Shape Ups for that....they work.
