I have become a huge fan of Ecco shoes for their comfort, but this particular style was so uncomfortable, I had to give up on them. The back of the heel comes up higher than most shoes, and it dug into the back of my heel every time I wore them, causing my skin to rub raw. Maybe it's because I got it in a patent leather, which is generally stiffer, but I think it's the cut. I have another pair of Ecco ballerina flats that feel like butter, and I have walked in those shoes for miles across NYC in total comfort. These still have better cushioning and support in the footbed than most other shoes, but the heel never "broke in" for me, despite giving them several tries. The shoe is also cut a bitt narrow in the ball of the foot. I have a developing bunion, and the angle of the arc of the top of the shoe hit at just the wrong spot for me. That's more of a problem specific to me, but I definitely think the heel issue would bother just about anybody.
