The Cable Setup
The biological wires that move your foot
Bones are the frame, but they can't move on their own. Your foot is rigged with a network of biological cables — tendons, fascia, and ligaments — that pull, spring, and hold everything together.

Step 1 / 4
Plantar Fascia — The Spring Sheet
A thick band along the bottom of your foot that acts like a rubber band. Every time you step, it stretches and then snaps back, giving you a free spring forward.
Springs, not levers
Your foot doesn't work like a stiff lever — it works like a spring. The plantar fascia stores energy when your foot lands and releases it when you push off. That's why running feels bouncy once you get going!
Mr. Bones says: I'm a fictional skeleton, not a doctor! This is for learning and fun. If anything hurts, stop and tell a grown-up you trust.
