Firstly, I LOVE KEEN.  I've had Keen's since their first sandal with the toe. (heck I still have them they are a bit worn).  However clearly someone designed this very very cool boot, but didn't try it on humans.  I couldn't even get my 8.5/9 foot into the 9 boots, they can't make the corner, I suspect perhaps the boot material was intended to be stretchier but wasn't so that you simply can't get your foot in.  KEEN - please oh please remake this next year with a stretchy boot so I can get my foot in and hell why not make it colorful like you other boots (I'd settle for blue or red), as all men's boots don't need to be black on black.
