I don't wear them any more, but back when I lived in Crocs, I fell during a rainstorm right there between Ice Station Cool and the fountain in Epcot. That concrete doesn't give and I'm too old and fat to be bouncing on concrete!

I thought I broke my tail bone.

After that I refused to wear Crocs in wet weather.

They were brand new for the trip, so the tread was good on them.
