Bears who are heel strikers like humans, unlike cats, dogs and many others animals, have eerily familiar looking back leg structure
humans aren’t really heel strikers, go run barefoot and you’ll realize why.
turns out slamming your heel into the ground hurts, what we use the heel for is standing on it.
Walking humans and bears definitely heel strike. I’m not talking about running.
even then we don’t put our weight on the heel first (unless we’re wearing terrible modern shoes that force us to do so), we put weight on the heel and forefoot approximately at the same time.
