I have a pair of Keen gore tex hiking boots. Bought them before I learned that gore tex is a waste in hiking boots, as the water gets in the tops anyway and then takes much longer to dry out. Also, with not that many miles, the lugs on one sole began delaminating already with the boots barely looking used. Bought Merrill Moabs for desert hiking 13 years ago and been using them ever since. The ankle support of taller heavier boots isn't as real as we'd like to think, as Mcswny mentions in his post above. I've adopted the practice of the hard core distance hikers: if it rains, or the grass is wet, or you have to cross an unbridged stream, you get wet feet. Keep hiking, they dry out faster than heavy leather boots. I also read that a pound of boot on your foot is like an additional six pounds on your back. At my age, I want to keep my load light.
I still have an old pair of Vasque Sundowners. Nice boots, but heavy as a tank compared to modern trail runners. I'm sold on Merrill Moabs (or similar) for cross country and boulder scrambling, not just trails that are smooth as side walks.
