I have a terrible time finding shoes that are comfortable - I must have weird feet.  These are comfortable enough to stand or walk in all day, and you can wear them for work or dressier ocassions.  They are fine for work, though they probably wouldn't suit a lawyer or a wedding. They are not as comfortable as my previous Keen clogs are run a little bigger.  I usually wear a 7.5, always take an 8 in Keen and these in the 8 are a tiny bit big.  The uppers are a little less flexible and more stiff than in the usual Keens, but for the price, certainly worth it.  They are great for plane travel as they are easy on-and-off and suit the need for a lot of walking.
