Feet are amazing! They are an architectural wonder, in terms of how they are designed and what they can do.
Your feet absorb 2-3 times your body weight every time you stride when you run. And they absorb up to 3-4 times your body weight when you jump off of something.
They also give you "spring" that helps you to jump up, and gives you propulsion when you walk and run.
This video shows how feet are designed to do that, and how you can find the spring and shock absorption in YOUR amazing feet.
Happy exploring!
