UPDATE:  left these out in the sun for a few hours, like one might do with garden shoes, and they shrank from size 11 to size 10.  Since I am size 10.5, they are too small now.

These are great garden shoes.  They fit pretty true to size.  This means that if you are a half size, you are either too big or too small.  Not sure why Crocs can't make half sizes like every other shoe maker.
