I have 4 pairs of crocs, so I generally know what I'm getting into when I buy a pair.  I like them, they're comfy and I wear them all sorts of places.  I even got a pair for my husband, and he likes his.  I had heard about the China/Mexico sizing difference, but had never experienced it as all of mine were made in Mexico up to now.  My Cleos were made in China and they are too narrow and small.  I wish I had bought them at Amazon so I could return them.  Bleah.  I now have my first pair of uncomfy crocs.  I wish there was a way to know where it was manufactured before you buy it.
