I have a couple pairs of the Alice Crocs that I've owned for about 1 1/2 yrs.  They're a comfortable shoe that I wear all the time.  The shoes mold to your feet which is great, can be washed off, aren't clunky, and can take a beating!  I wear a 6 1/2 and I wear a size 6 in Crocs.  The shoes will stretch a bit so half sizes should go down instead of up to the next whole size.  These get three stars since the plastic attachment grommet can rub on my arch if it's hot out and my feet get sweaty.
