Hi Ken, I'd second Salomon, they're light and mine fit me like slippers. If you're looking for a lower boot, the X Ultra Mid 2 might be better than the Quests in that respect, although the quality (and cost) is higher on the Quests. Also, if you wear Hi-Tec (I used to and swapped to Salomon), then you'll almost certainly need a bigger size in the Salomons, half or even full size up. I have a bad knee and the Salomon's are world's apart from my old hi-tec in terms of suspension/bounce and takes a lot of strain off the joints.
I also have a pair of Berghaus Hillmasters, which are heavier but more robust and more waterproof. That being said, the type of walking you do they might be considered 'overkill'.
