Flat Feet, Elevated Heels and Pectus Excavatum

My theory about flat feet and pectus excavatum: The cause of extremely flat feet is genetics and elevated heels (in most cases). I am sure about it. Since I stopped wearing shoes that lifts up the human heel there have been a dramatic change of my feet. The feet have become much higher and increased in width. The perimeter right above the feet has increased by around 4 cm and the feet have been lifted up on the middle just by walking (no specific training).

I believe that there is a connection between flat feet and pectus excavatum. Flat feet is caused by high mobility in the foot and pectus excavatum is caused by high mobility in the thorax. The connective tissue that binds and holds together the bones and muscles are very soft in both these cases.

Why do ordinary shoes make the feet flattened? When the heel is elevated the pressure on the forefoot will increase dramatically and cause a tension in the foot and make them a little longer, thinner, less in width, and more flattened. People with flat feet should put more of the weight on the heels and the opposite side to the arch by lower them to the ground. Barefoot/zero drop shoes will make that happen. Based on my experience, I can make the following conclusion: I believe that ordinary shoes can cause problems in the whole body because every single part of it will be more or less affected.

                                         
1. The perimeter in this area: +4 cm.
2. My feet have started to develop an arch.
3 .The big toe is pointing almost completely forward (not to the side).
