These are the only flats I have ever owned that I did not have to break in first.  They are extremely comfortable.  I frequently have an issue with the heel of flats being too tight at first and I have to deal with blisters and/or wear bandaids for a while until they are broken in. That is not the case with these flats! They are comfortable right from the beginning.  I also like how the sole is supportive and not too thin.  I have already bought these in two colors and am going to buy more.  They are the best flats I have ever owned and are worth the extra money.
