If you truly mean stalking such as bowhunting where ranges are about 40 yards or less then I use Merrils. They have a very soft, say it again SOFT sole. Vibram sucks like the hind tit for stalking. It is hard, clunky, whacky, cracky and just fit only for the garbage can. It also makes your arches hurt because the sole won't bend. The most gawdawful stuff ever put on a boot.
I have also taken my boots and had a "gum" soles put on them. It cost about $20.00 but really quietens them down.
Did I mention that I don't like vibram.
