I've worn the Keen Presidio for several years, probably since they first came out. Probably the most comfortable shoes I've EVER worn.  they have plenty of toe room, good support for being on your feet all day.  I've never had any issues with the leather wearing out, ripping, etc.  They last forever.  Until I wear the soles smooth!  I have purchased them in every color and (seriously now) I've begun buying extra pairs and putting them away for later, because I fear (like most makers) that eventually they will discontinue these and I won't be able to get them any more!  So I'm prepared for the next several years at least!  Oh, and they're waterproof.  Maybe it's "water resistant", I don't remember specifically, but when you walk in puddles or up here in minnesota 6 months of snow and slush, your feet stay dry.  They don't have a gusseted tongue, but no water gets in between the sole and the shoe, or through the side leather.  All in all my Go To shoes when I know I'm going to need to be comfortable all day!
