These are not the most comfortable crocs i own. And I own a lot of them.<br />It's not the heel height that bothers me, but the part where the leather meets the rubber bottom of the shoe (at 4 different locations). I can wear them comfortably for a few hours, but cannot walk on them for hours. I was wearing them all day, but one day, I had to walk all morning (about 3 hours), and my feet started to peel at the four sections I mentioned. On both feet. Had I continued walking without band aids (yes, I had to use 8 of them), I'm pretty sure I would have blisters now. As It was, it was hard to walk even with the band aids, and I had to switch shoes.<br />But unless I'm doing heavy walking (shopping all day at the outlets, or being a tourist, or doing a museum tour... etc), they are comfortable.
