These run about a half size smaller than regular crocs. I’m hesitant to exchange for the next size up as I fear they will be too big. I recently had to return a pair of these to the official store and the girl who works there said it’s because the ones with the band are thinner. Not true. They are not the same length...see pictures...I have the Drew Barrymore’s, they have a band and they fit and I have the regular crocs. Both of these are the same size. So if your current crocs just fit your feet without much extra room I would order a size up.
Just wanted to add that when I was packing these up for return I noticed one was shorter than the other. I guess that explains why the left foot was hitting and the right was just about perfect.
