I love aerosoels because I consistently take the sample size across styles, and the styles I've selected have been equally comfortable.  There is not good arch support but these are flats and I don't expect good arch support.  My favorite about aerosoles is how long the heel and sole lasts which is as long as the shoe.  As a matter of fact, I have an old pair which have been worn thin on the inside and still have a good sole. Hence the 5 star rating.
