I had just purchased another pair of Keen boots which I love (Kaci)...then saw these and the price is so right.  I live in rural Northwest Montana and need an easy to put on boot to go out with my dog multiple times per day (working from home office).  I have tried various wellies and they either do not fit well or soles are too slippery on wet/uneven ground.  These are not only comfortable on my feet but the sole has been good on snow, icy driveway and slushy/rocky ground.  PLUS, they look great!  I have the black - would love a pair of each color.  Re fit:  my foot is kind of square and I did have to go up a 1/2 size for my toes.  They slip minimally in the heel.  Both pairs of Keen boots loosened to great comfort in the first week but this style is noticeably more narrow than the Kaci.  The soft lining makes it comfortable for a quick outing with no socks also.  They seem very well made as has every Keen product I have. I have been an Ugg customer for 12 years and become unhappy with quality for $$.  I think I am being converted!

***May 2013 edit.  As noted, these are not a waterproof boot and I didn't expect to walk into a river or lake and stay dry.  But based on my experience in light snow, I thought they would do fine in my woods after rain.  Not so much.  The wet grass and flaura of the woods soaks these through and my feet also.  BUT, as noted, they are not sold as a waterproof boot.  I have the Keen Kaci which are waterproof and those do keep me dry.  I'm still happy with these - they continue to be comfortable.
