I work in a hospital and got these to wear for my 12 hour shifts.  One of my feet is almost more than a half size bigger than the other so, my left foot is a little less happy at the end of the day.  But overall - I get a lot of compliments and they are much more comfy than the butt shaping type sneakers I spent $100 on.  A few sticklers for rules told me the "open" front was non-regulation for hospital footwear.  I wear socks, so pooh pooh to them.  I spray all my shoes with serious germ killing stuff when I get home every night - so I love that they are very "cleanable."  I have the more common variety of clog that is unisex & wider and flatter.  I'm always tripping when I walk fast in those.  Not with these clogs.  They stay by the front door and I generally choose my Dr. Scholl's if I'm running out to do a quick errand as they look sweet with jeans or tights or a skirt.  I prefer something with a bit of a heel - it just feels more comfortable to me.  I'm thinking of getting another pair just for non-work.
