I've got originals shoes and the crepe soles are so slippy on wet ground. They look really sensible but they are dangerous when wet.
My work is community based, and if I go in anyone's house where the carpet is less than clean, they also tend to stick to the carpet, and it is actually quite hard for me to lift my feet off the carpet and they make a sort of tearing noise so it is obvious I am stuck.
All in all the crepe soles have been an unexpected source of both danger and embarrassment. Very comfortable though
