Edit for more clarification.
Could someone provide a more physics, structure of cell, sharing of weight over cells, based explanation?
In: 25
The skeleton forms a frame which supports the majority load of your body weight (very much like the metal frame of a building) to distribute it throughout your body. Muscles support your Skeleton to help keep the frame in place and again help distribute the load.
Skin cells on feet do get crushed, but only in a sense. This is why you develop rougher and harder skin on the bottom of them, because the body forms extra keratin in these cells to make them more resistant to damage.
Edit .. Ooops I forgot muscles!
Same reason your tires dont get squished by your car’s weight. They do, but they are designed and built to handle it, and are perfectly suites to operate under the preasure.
They do, and then they bounce back. This is why sitting/lying down lets your feet relax after you remove the weight from them.
They’re ‘built’ to withstand it. The structures of your bones, tendons, muscles, etc. are working to support your weight.
What do you expect?
The bodies response to pressure is more skin, or callouses. Corns are basically what happens when skin gets “squished” in the foot in the wrong direction from poor footwear.
So short version, skin gets thicker to compensate.
They’re not just cells, they’re skin, muscle, and bone – meaning the cells have formed complex structures that can do more than their individual components.
If you think about it that way, if your skin muscles and bones couldn’t support your body weight, we’d never have been able to evolve in the first place.
If you could somehow focus your entire body weight onto the area of a single cell, it would presumably crush it, but that’s not the situation.
