Have been wearing these for quite awhile.  Great for people who are on their feet alot.  I had to send back my first pair to get a smaller size (I would say they run big).  Love the vents all around shoe.  No problem wearing with light tp medium thickness socks.  I even wear them now in the winter months; we don't get snow here.  When rain is predicted, I wear my tennis shoes, and I can't wait until it clears up so I can go back to my Crocs.  Crocs are a bit pricey, but they always have been.  Still would recommend, especially if you're on your feet alot.
