Abstract: shoes are indispensable necessities for people.

It can not only promote a group of clothes and chew, but also our health.

From the comfort and simplicity of flat shoes to the seduction and fashion of high-heeled shoes, the footwear industry is constantly changing.

Heel

The height.

And the latest research shows that

Negative heel shoes

More conducive to human health.


Shoes are indispensable to modern life.

The ancients said: the journey of a thousand miles begins with a single step.

If you don't have shoes, you can hardly imagine.

If we mention the science of shoes, the first thing we must think about is sports shoes.

Although in 1960, Ethiopia's marathon athlete bebbe won the world champion, but with the retrogression of sports technology, the era of barefoot Daxian has gone forever.

In ancient sports, sports shoes are boots and equipment.

The manufacturer's development of sports shoes is no less than that of the martial arts competition. It can be regarded as spendthrift and spendthrift. The cost of a pair of running shoes can be as high as tens of thousands of dollars.

The superstitious design of sports shoes has different requirements on the sole of shoes at different sports and even different venues. Therefore, a lot of sole parts can be freely replaced to keep them in constant demand.

Liu Xiang, the famous hurdler, had long decided to replace the short pins of running shoes with nails before the competition, and achieved satisfactory achievements. He also called long nails as his "secret weapon".


As the saying goes, life depends on exercise.

Ordinary people's standing and walking is also a sport. Should they have corresponding health equipment? Because people are upright, their weight is all in two feet.

When standing and walking, shoes and feet must be combined into an organic whole.

So the science of ordinary people's shoes is also the sole of shoes. Unscientific design is not only bad for daily life, but also harmful to health.

A typical example is a series of foot diseases caused by high-heeled shoes.

At the same time, high-heeled shoes also directly affect the health of the spine.

Therefore, doctors are particularly suggesting that patients with low back pain and cervical spondylosis must pay attention to the choice of shoes and avoid wearing high heels.

This is a major issue related to human health. Therefore, the study of living shoes is far more important than the research of sports shoes.


The relationship between people and shoes is the relationship between the building and the foundation.

No one will be careless about the design of foundation. The foundation will also set up a special foundation sub committee to conduct in-depth research.

But for shoe design, it has never been so strict.

The outdated and stereotype of traditional views seriously hampered the development of shoemaking research and caused more health problems.

Clinical materials show that "foot diseases, except congenital malformations, are acquired acquired foot diseases."

It is estimated that around 1/4 of the world suffers from varying degrees of foot disease. "

The medical community has confirmed that all body diseases are directly related to shoes.

And a lot of data confirm that barefoot is more conducive to the health of feet.

That is to say, from the angle of health of feet, shoes are harmful and useless.

For a long time, no real cause and countermeasure had been found, so we had to call it "barbarism".

This is undoubtedly a great satire for the highly developed modern science.


  

Love and hate

High-heeled shoes


High heeled shoes are the love of fashion motherhood. They are usually magnificent and magnificent like artworks.

But at first, the feeling of wearing it must be careful, such as thin carbon, as the song says: "high heel shoes step on steady steps".

Along with torture, all kinds of diseases follow.

In terms of shoes and health problems, the high heel shoes' health damage is the most typical and prominent. It is mainly manifested in the following aspects.


Forefoot disease.

Common foot diseases such as hallux valgus and interphalangeal neuroma are related to moderate stress.

High heels make the center of gravity move forward, and the power of the sole is doubled.

Once these two diseases are formed, walking can be greatly affected, even wearing shoes with deformity is very difficult.

In addition to surgery, there are no better decisions.


Flat foot syndrome.

Plantar fasciae laxity is an important cause of flat foot disease. It is located at the sole of the foot, maintaining the stability of the arch as the bowstring.

The higher the heel is, the longer the rear arm of the arch is, the greater the tensile force (tension) of the plantar fascia.

If the tension is too long and the plantar fascia is loose, the arch will decrease, which will cause flat feet.

The relationship between the height of the heel and the tensile force of the plantar fascia can be clearly reflected from the structure of the sole.

Many shoes have a steel plate called the "hook heart" in the center of the foot (which is called the plantar aponeurosis).

It is used to strengthen the sole of shoes.

The higher the heel is, the higher the strength of steel hooks is, otherwise the soles will be easily broken.

The higher the heel is, the more the sole needs to be reinforced by steel hooks, and the human plantar fascia is helpless.


Ankle injury.

Ankle injuries are commonly known as "sprained feet". Wearing high heels is a common practice.

The right ankle is prone to turn inward during walking and exercise.

People themselves are constantly adjusting this turnover force to maintain a balance, but after wearing high heels, the ability to adjust will be weakened, and easy to cause sprain.

The higher the heel is, the greater the potential energy to turn inside, the more serious the injury level will be.


Low back pain and cervical spondylosis.

The important reason for lumbago and cervical spondylosis is that the curvature of the spine is too large. Because the spine is connected by multiple vertebrae, the contact surfaces of the two vertebrae are nearly three-dimensional.

When the posture is tall and straight, the contact between the vertebrae is between the surface and the surface, the force is evacuated, and it is not easy to damage; when the spine is bent, the contact surface between the vertebrae becomes smaller, the force tends to be concentrated, and even concentrated to a point, the pressure increases rapidly, which is easy to damage the vertebrae.

High heel shoes make people's center of gravity move forward too much, which will inevitably cause the pelvis to tilt forward, the curvature of the spine to increase, the centralization of the lumbar vertebrae and the cervical vertebrae, and easily cause injury. The accumulation of such injuries will eventually lead to lumbago and cervical spondylosis.


Specious middle heeled shoes


For a long time, heel shoes have always been considered to be the most healthy ones, and without any adverse effects, they become the two poles of the high-heeled shoes.

In the footwear industry, it is regarded as a rule of law, and designers try to match their products with standards in order to sell well.

Because of health considerations, consumers often choose middle heels.

Those women who are afraid of high-heeled shoes are fond of the same kind of middle heeled shoes that can also be swayed.

In this way, the middle heeled shoes naturally become the mainstream products of footwear.


But this theory sometimes makes people doubt that heels and heels are heeled at the back of the sole, though highly different, but it is difficult to draw a relative line.

For example, 3.5 centimeters of heels, some people think that they are high heels, some people think they are middle heels, and at first there are "middle high heels" pitional names.

Since there is no absolute limit, how can it have the opposite effect? High heeled shoes are a healthy enemy with disadvantages and no benefits. Just a little shorter middle heeled shoes is a healthy angel with a perfect flaw. If we look at it with jealous eyes, we will have more problems.


The center of heel health theory is that it can make the force of the plantar average.

It seems very simple to explain: high heels make the sole of the foot stronger than the heel, which is not conducive to health.

Only the middle heel shoe can make the force of the foot smooth, so it is the best.


In fact, only by looking at the anatomy of the foot, we can see that the structure of the foot is obviously uneven. The ad abdominal exercise machine is very strong in the calcaneus and strong in muscular ligaments, while the bones, muscles and ligaments in the front foot are much weaker.

From the perspective of human brain mechanics, the skeleton of the calcaneus is similar to the longitudinal superposition, the structure is stable, the gravity conduction is smooth, and the bones of the front foot are almost arranged horizontally. When bearing, they must be maintained by the strength of the muscles and ligaments. They belong to elastic structures, which are easy to deform and are not suitable for bearing.

In a word, no matter from which angle, the forefoot's bearing capacity is far less than that of the back foot, so that the front and rear feet are subjected to the same pressure without reason.

It will damage the delicate parts, which is also the cause of foot disease in the forefoot.


Look at the so-called second advantages of middle heels, namely, slowing down vibrations, maintaining the spine and brain, and how to get red blood on the face.

The disease caused by vibration is called vibration sickness, which reduces the efficacy of the nervous system. Conditioned reflex is restrained, nerve endings are damaged, and vibration and pain can manifest itself.

It shows that the arms are numb, sour, painful, and have a sense of ant walking. The arms will also be rosy, cyanotic, muscular weakness and muscle atrophy.

But vibration sickness belongs to occupational disease. It is the result of long-term stimulation of human body by high frequency mechanical vibration.

Most of them are in flexible vehicle drivers. For example, the vibration frequency of a tractor driver is up to 50 times per second, and the high speed gear can be up to 100~200 times.

This shock and the shock of human motion are two completely different concepts.


In order to prevent panic in vibration disease, the 108th domestic (Organization for mechanical and vibration) Technical Committee fourth (human body vibration response) Chapter specially studied the impact of vibration on human health, and finally concluded that "walking and Mercedes" are natural ways of human movement.

Especially when it comes to the work of muscle realization, it can be considered that the vibration stress that arises should not be harmful in normal circumstances. In order to lose the indication of vibration in the upright posture, it is beneficial to compare the response of people caused by vibration when walking or running.

Since this vibration is beneficial, why should middle heeled shoes be prepared against it?


It is boring that the shoe heel was not first used for walking, but for riding.

When the nomads are riding, the heel can keep their feet firmly stuck to the stirrups, and they can also stand up and use weapons when fighting.

Following the domestication of nomadic people everywhere, heel shoes have gradually spread and are widely accepted.

This is for practic
