I finally got crocs after working in the medical field for a year and a half.  I hated ruining my sneakers all the time, spilling chemicals, blood etc.  These definitely do the job of protecting my feet and I love that they are wide and roomy.  However, they are not as comfortable as I was expecting.  There is no cushioning at all, they are quite stiff.  The indentation under the toes is a bit annoying if your foot doesn't stay directly on it, I'm already starting to get a blister from rubbing.  All in all, they do the job.  But, don't buy these if you're looking for a lot of comfort.
