I wear a size 9.5 to 10 narrow and have a hard time finding nice flats that do not fall off my feet.  I have been looking for a nice black leather flat shoe for over a year now, and this is the first one I have found that is really good looking and fits well.  I have never worn Naya before, but they are made very well with a super comfortable and padded insole.  Hopefully, I have now found a brand of shoe that I know will work for me in other styles.  I also got a fantastic price this time!!
