I purchased these as a replacement for a pair of slip on merrils that my husband had worn to death.  He leaves these at the back door for quick trips to the mailbox, grocery or garage.  Lately I have to laugh as they are showing up on his feet when going out to dinner and even church.  They don't look anything like the plastic crocs more like a sport shoe; I think the leather upper is what really sets them apart.  He says they are very warm and comfortable.  He wore them out on the ice and snow this past week and praised the great traction they had.  I am considering ordering a spare pair to have when he wears these out!
