I am the biggest KEEN fan ever.  I have at least 5 pair.  I am on my feet moving for 12 hours at a time.  I tried these on at a store and thought WOW the usual great KEEN comfort. After purchasing these on Amazon I found that they are not as comfortable as others that I own.  They come up a little too high under the ankles, nothing horrible but they just don't seem to have the support like: the Briggs or the malibu.  I do like them and have gotten many compliments I would probably opt for a different pair to work long hours.  They are still a great shoe, I wear them on shorter work days and to go shop or run around town. I know this is not very helpful but if not for the long continuous hurry at the job I would still recommend these shoes.
