What is the "over pronation" that causes all foot ailments?

This is a channel that provides information on foot health sent by Japanese foot expert "Nakajima".
Who is "Nakajima" (as of September 2021)
I have been working as a healer since 2012.
Invented a natural way of walking "native-walking" in terms of biomechanics of the human body.
By teaching "native-walking", I lead many patients suffering from various foot symptoms to improvement.
In particular, I have made great achievements in improving hallux valgus, and there are more than 2000 cases of improvement measured with reliable measuring instruments used by many universities and hospitals.
Currently, I am working hard to popularize this walking instruction method, and more than 70 treatment clinics have introduced it in Japan.
In recent years, I have also been conducting joint research on walking with major companies.
"A burdensome way of walking" is the cause of various foot diseases.
I started UA-cam in 2020 to spread that if people improve it, many foot symptoms such as hallux valgus will improve dramatically.
