Footing your shaft will have no impact on getting through a hogs shield. It may help maintain arrow integrity if you hit heavy bone, but my experience is that if you hit heavy bone going in, you have big-time problems, no matter what arrow you use. Not to mention if you hit heavy bone, you are not likely to be getting into the vitals very much. I guess what I am saying is, if you feel like footing your arrows, that is great, but it is very unlikely it will make a difference in weather or not you successfully harvest any given hog.
