After wearing these for two weeks, one of my daughter's boots is shiny and the other one is dull/matte.  The "patent" literally peeled off of one boot, while remaining firmly intact on the other one.  Also, the boot that peeled is severely creased, while the other is not. So now we have one shiny boot that looks fine and one that is dull and creased and looks terrible.

As for sizing, I have found that these are a little smaller than normal crocs.  My daughter has a pair of regular crocs that fit loosely, so I bought these boots in the same size.  They seem to fit smaller and are slightly difficult to get on and off.

I'm not happy with the inconsistent wear, but I decided to give 3 stars anyway since they do keep her feet dry.  I haven't decided if I'll keep them or if I'll try to exchange them; there's obviously something weird going on since one boot is fine and the other is peeling like a bad sunburn.
