I'm new to these forums (not to backpacking) so please bear with me.

I've been backpacking with my father for about six years now, usually 2-4 day trips up into the Wind River range in south western Wyoming.

In all cases, I've had the problem of crap getting down into my boots, pebbles, grains, pine needles, etc. In this last trip (about a week ago) I had to take my shoes off and clean them out at least three times on the most recent hike out (about 6 miles, descending ~2000 feet).

I use Keen Targhees at about a mid cut, but I'm even considering buying some higher cut boots (almost like the ones enlisted military men use). Just to prevent a wandering pine needle from calling my wool sock home.

Any recommendations? Has anyone tried combat style boots for hiking before?
