Just make sure that you don't pull the feet all the way to the front, you should instead have the feet tilted a bit inward (push them in following the arrow) so the center of the feet is in line with the center of mass of the body.
if anything, PE should come up with a clip to hold the red heel in place instead of the latest silly weapons pack.
