I really like Mel's jellies and wanted to branch out into the shoes that look more like standard flats.  Unfortunately, I have the same problem with this shoe as I do other flats - heel rubbing due to my narrow heels.  Additionally the inside of the shoe (that falls on the top of your toes) is not lined, so your toes stick a bit.  Otherwise, I like the look and they have good cushion in them, so if you did not have narrow heels they would probably be a very comfortable all day shoe.  Really like that they are the standard Mels - waterproof, recycled and scented.
