The ball of the foot is doing the pushing at that point, and the ball of the foot finishes the liftoff. Try and take a few steps where the ball leaves the ground before the heel, you'll see.
- WalterSear 9y agoThe ball of my foot may be the last thing to leave the ground, but when I run barefoot style, I'm pushing off with my heel.

- sgk284 9y agoYour heel doesn't have leverage to lift your body off of the ground. If your heel is leaving the ground it's either your knee lifting it or your toes pushing it. In the gif you linked, and in proper running form, you push with the balls of your feet. Your ankle / heel system is solely a fulcrum that doubles as a dampening spring.
- kiriakasis 9y ago"pushing" isn't the only way to apply force. from the gif the ball of the feet start and end the "pushing", but this is unrelated to how much lifting you do with the heel
- Shikadi 9y agoIt looks to me like you're ignoring inertia, the force is highest right when you switch between catching yourself and pushing off
