While they look great, don't be fooled, these will never be comfortable to wear.  I have now worn them 6 times and all 6 times have had to take them off after 60 minutes because they hurt my feet.  Something about this design will create a pinch area in front of the ball of your foot.  That is uncomfortable enough, but with the heel design these are also very easy to walk out of as well.  Count on the lining to shed every time you wear them as well.  Most Crocs that I have bought, after about 30 minutes of wearing them they have conformed to my arch and my foot pattern, I don't believe that these ever will.  (Or if they will some time in the future.....I don't know that I could stand to wear them -that- long to find out.)  Stay away, you have been warned!
