I have a wide, straight foot with low arches.  I am a mild over-pronator.  I use these shoes for casual wear and working around the yard.  The Addiction is true to size and width.  The straight last fit me well.  The arch support was good for my flat feet.  The pronation control is a bit strong for me.  The shoes are well constructed which is something you cannot take for granted now that everything is made in China.  I don't have a lot of options for my feet and these Addictions are the best of many I've tried recently.  I bought a second pair in the leather to wear at work.
