I do most of my grouse & woodcock hunting in N. Michigan in tennis/running shoes with WalkFit arch supports, at least until snowfall, then I switch to my lightest weight uninsulated Muck boots.

And I shot a moose on a British Columbia mountain side last October wearing tennis shoes, but he was not up high enough to be in the shale/rock.

I get a kick out of the guys wearing high tech mountaineering boots hunting the gentle, rolling hills in here in Michigan.
