I have a pair of tan Keen Saratoga and I love them.  It's got just enough of a heel that gives my foot the support it needs and even though I normally like to wear shoes that anchor down my heel with some kind of strap, my tan pair was such a pleasure to wear out and about (especially in areas where you might feel the sudden urge to kick shoes off quickly such as planes, etc...might take place) made these one of the best shoes out there, as far as I was concerned.  Why the low rating on the Beet Red ones?  The strap over the arch was so loose that I can't actually wear them at all.  How it got so stretched out (especially compared to the tan pair that I have) is mind boggling, but the strap doesn't provide any anchoring of the foot to base, thus I can't wear them at all. If only they had a velcro strap where it could be tightened.  Honestly, I've been trying to think of a way to make the strap shorter so it offers the support I need, but it would involve cutting the leather and probably wouldn't hold together well.  Truly disappointed...I was really looking forward to have a back up pair in a really snazzy color like this.
