When a person stands on surface. The gravity force of body on a surface is greater than the normal force by the surface upwards .
The pressure on toes or soles is as a result of two equals forces , one is the force of ground upwards and the other is force downwrads taken from the weight” this force is always less than weight”
Come back when you have some math to support your claims.
You might be confused by the repeated paragraphs.I edited it.I mentioned that the forces are related to each other mathematically , which implies simple proportionality.
I'm waiting for you to supply the math shows that toes can't bear the weight of the body.

It is biological that this phenomenon appears only to humans.
Bones are stronger than concrete.On a weight for weight basis tendons are stronger than steel.
But this is actually a phenomenon beyond physics.
It is not just about breaking bones or tendons.It is a whole collection of factors. The 80 kg mass will cause huge pain, cutting flesh, breaking joints, and above all pressing the toes extremely hard.Compare standing on concrete and putting 80 kg concrete on ones toes.
The 80 kg mass will cause huge pain, cutting flesh, breaking joints, and above all pressing the toes extremely hard.

So why did you state earlier 'It is biological that this phenomenon appears only to humans.'?

The phenomenon related only to gravity on a human body that is the toes won't bear for instance "equivalent to human body " 80 kg mass put on it it.That will press the toes extremely hard.
To humans only but not to other masses, and I referred to humans only because it is a better example " everyone can test it"
