I don't have narrow feet, but I really wanted these and all they had in stock was a 10N.  Beings I normally take a 9M, I took a risk and got these in the 10N.  I figured if the bed is going to be notably more narrow, then I should go up a size.  It works for me, although after only one full day of wear, my feet did start to hurt as the boot is narrow on the sides.  I've worn them 2-3 times, all day, now.  Seems like they're getting better- wider- more comfortable.  I really like the shaft height, the medium chocolate color (TRUE to color) and the unique style/design and the height of the nice-looking heel.  Clarks is a good brand - nice shoe that seems to be well made, even if it is made in China (what isn't these days?)
