overbo, NO stalking boot is going to be really quiet on hard ground unless it has a really soft sole. I've guided lots of hunters and suggested that, they bring soft soled stalking shoes, none of them do that and bring something that is sold as "stalking sneakers" or that sounded quiet at home on their carpeting. On soft ground, any flexible boot with a thin sole will work. I have found three that worked on hard ground, Rocky 911's which aren't made anymore, Clarke's desert boots, which aren't really made for hunting, but work great in Africa or Australia during the dry season and Russell PHII's. I really like the Russell's, I can order them just the way I want, they have soft gum soles and were designed by a professional hunter, not some marketing guy!
