The soles of these shoes are very comfortable and do fit the arch well.  The problem that I have had and my sister has had is that the back of the shoe digs into the back of your ankle.  I bought them to walk around Disneyworld, but the blister was not worth it.  If you decide to purchase them anyway, definitely get some mole skin or something to protect your skin.  In the future, I would probably only buy orthaheels that have an open back to the shoe.
