Do you wear your hunting clothes here and there all year long as well? If not, why do you wear your hunting shoes all year long? They are part of your hunting clothes after all. You should only wear your hunting boots while you are hunting. Buy another pair. I don't care if you use all the baking soda in the world, it is unlikely you will wash away a year's worth of odors that have built up. If you hunt in those boots, you might as well go hunting in your everyday clothes.
