Unfortunately, I have reached the age that I need comfortable, flat shoes with straps or ties.  Have searched high and low for something that didn't look to "old-ladyish" from a 62-year old standpoint.  These shoes fit the bill.  They are not only comfortable (cushy insole) but they come in a wide range of widths from narrow to extra-wide.

They are true to size (I wear 9C) and I have now purchased them in four colors that I can wear year round.  They would probably be more stylish without the strap, but the straps are mounted further back from the toe so don't look quite as bad.  They go with everything from jeans to dresses.
