Upon good reviews and knowing crocs in others styles are known for their comfort, I bought these and started wearing them immediately.  I wore them today for the first time for a few hours.  They are very uncomfortable and are ready to give me blisters along the area of the strap closest to the ankles.  Not only that, but since they are made of plastic, nothing breathes and my feel get very hot and sweaty.  I guess it works with other Crocs since they are not as form fitting?  I should have worn them around the house a bit before I wore them outside.
