Do You Know That You Have Eyes on Your Feet?

Herman, you must be crazy! How can you have eyes on your feet? Everybody knows that humans only have two eyes, on their faces.

No, no, i am not out of my mind. I am not talking about eyes literally, but i am talking about the sensitive nerve endings on your feet. Do you know that the most sensitive parts of the body includes the hands, feet, genitals and lips.

Sensory homunculus

Look at the diagram of the sensory homunculus. This is how much surface area the brain dedicates to each bodypart. The physical size of the bodyparts represent the sensitivity of that part.

So when blind people feel their way around using their hands, they are actually seeing their way around with their hands. The feet are not as sensitive as the hands, but they are remarkably sensitive in the absolute sense. There are people without hands who can perform things we take for granted using their feet, like writing.

In the not so extreme use of the feet, grapplers use their legs and feet to manipulate their opponents just like how you use your arms and hands.

Ever imagined how life would be like if you go around blindfolded? That is exactly what happens when you enclose your feet in stiff, thick soled, thick heeled shoes.

Just as you would be out of your mind to go around blindfolded, it is a crazy thing to walk around encasing your feet in a cast that you call shoes. Your feet need to move more. There are 28 bones and more than 30 joints in your foot. If they were meant not to move, God would have created them to be made of one bone.

There are some good general purpose shoes out there in the market like Adidas Jawpaw and Vibrams. Get these if you need to wear shoes. Otherwise try to be barefoot as much as you can.
