I have a wide, flat foot and own several pairs of Keens.  I got this boot to wear with jeans and slacks.  It looks great with both.  I ordered my usual size 9 and the fit is perfect.  My feet usually hurt in any type of heel after 30 minutes.  I can wear these all day.  I was worried that I couldn't snap them over my cankles, but they are a perfect fit there, too.  I'm only 5'2" and love the extra height these provide.
