I ordered these because they look beautiful in the picture and they are listed synthetic (no leather***).  While I still think they're unique and attractive, they KILLED the bottom of my feet!  There seems to be very little inside padding for the sole of the foot (the ball of the foot especially) and the sole of the shoe was very hard--which due to the lack of inside padding was obvious to the bottom of my feet.  [It literally reminded me a bit of Steve Martin's recording "Cruel Shoes"!]  The bottom of the shoe is also not flat, so I felt completely unbalanced when I tried to walk as I seemed to tip to the right or back as I walked.  I am amazed that someone else found this shoe comfortable, though I will say that the top of the shoe (tongue, etc.) seemed comfortable--not that this could make up for the pain in the sole of my foot!  I am returning this shoe ASAP!

***Rockport finally responded to an email I sent 3 months ago and said that NONE of their shoes are without leather.  They said that all of their uppers contain some leather or suede, apparently regardless of what is listed!
