Guys hit there feet when it is done wrong, don't be afraid. Get some good protection (chainmaille socks or booties with a metal srap underneith) and try it out. When everything is lined up ( head, shoulders, hips, knees, feet) the axe has nowhere to go but directly between your feet. Practice on round wood, not that square crap we chop around here. It's really tough to slice 'n dice your feet on a big stick, especially after you put in your opening blows.
