I am a medical resident, and I bought these shoes to wear when I'm on call or in the ER.  They are extremely comfortable, even after I've been on my feet all day.  I also love that they're easy to clean.  If something (blood, etc.) drips on them, I just wipe it clean with an alcohol or bleach wipe.  I haven't had any problem with the liner smelling, as some reviewers mentioned.  I bought this style because I like shoes that I can slip off and on easily when I do get a chance to sit.  I would definitely recommend these shoes.
