Is It Safe To Wear Flat Shoes?

The health problems of some beautiful but uncomfortable shoes can be attributed to high heels, pointed shoes, thigh boots and frenties. Compared with them, other shoes are much more comfortable. Are they safer? Not necessarily. Some shoes are comfortable to wear, but it is easier for you to ignore safety hazards.

First, Arch of foot Physiological significance

The arch of human foot, like arched bridge, is the guarantee of body stability. The arch is an integrated system consisting of joints, ligaments and muscles. Its flexure and elasticity can adapt to uneven ground, bearing load and shock absorption. Our feet bear the weight of the whole body. Any changes in the physiological radians of the arch will seriously affect the bearing function of the arch, as well as the maintenance of walking, running and body posture.

From the foot arch, we can see that the lateral arch (BC) has a larger contact area with the ground, which increases the stability of the body during standing and exercise. The medial longitudinal arch (AC) has greater curvature, which makes the foot more elastic and can partially offset the impact in motion. The transverse arch (AB) is the metatarsophalangeal joint formed by the phalanges and metatarsus in the anatomical bone of the foot. In the process of human movement, the flexion and extension of the metatarsophalangeal joint produces a forward force.

　　 Flat shoes are not equal to health.

When walking normally, each foot must pass through pedaling (landing on the heel), rolling (gravity shifting forward, one leg in swing stage), and pedaling (the plantar toes joint flexion toe pushing off the ground). The foot arch allows gravity to move forward from the talus of the ankle (the weight of the human body, the bones of the ankle and the bone of the lower leg), to the metatarsal head, to the calcaneus backward, to cushion the impact of the ground on the body, and to protect the brain and internal organs from shock.

Changes in the shape of the arch will affect its physiological function, which will cause health problems in severe cases. For example, when you wear high heel shoes, your feet are bent and your arch arch is reduced, which makes the ankle joint loose and unstable, and can perform lateral movement. The probability of sprain is greatly improved. Flat shoes, though not such a worry, may still have other problems.

Two, flat shoes are not synonymous with safety.

1. Shoe of sponge cake

Thick bottomed sponge cake is not as comfortable and safe as it looks. Thick and hard soles make the metatarsophalangeal joints unable to flexion normally when walking, resulting in obstruction of the gravity conduction process. The stable triangular structure of the arch itself also vanishes, replaced by a pure flat structure, which may cause foot fatigue, pain and other discomfort after standing or walking.

　 Comfort is not equal to health.

Too heavy sole also causes the center of gravity to move down, when walking is easy to lose the center of gravity, a little carelessness will be sprained and fall. And some thick and light sole causes the center of gravity to be on the side, which makes people feel heavy and heavy. So thick bottom shoes are not synonymous with safety. "Stilt walking" is also a technical activity.

2. Snow boots

Because of the lack of support for the arch of the foot, the snow boots with the same flat bottom and large sole hardness are low in the middle part of the feet. The flat sole causes great impact on the arch of the feet, which easily causes the fatigue and pathological changes of the hip and ankle joints and Achilles tendon. Moreover, because of the relatively large internal space of the boots, the back foot will slide in the shoes, shoes will not follow the feet, and the toes will be exerting when walking, so that the tendons and the fascia of the sole will be tense, which will lead to fasciitis and tendinitis and make the arch strain.

　 3, ballet shoes

Wearing ultra thin flat shoes (ballet shoes) is no different from barefoot walking. The flat sole does not conform to the physiological curvature of the arch of the foot. When the person walks, the impact of the ground will directly reach the spine from the heel along the leg bone, not only accelerating the degeneration of the plantar ligament, causing heel pain, but also causing injuries to the ankle, knee, hip and waist.

　 Three, temporary comfort may not be necessary. security

Because of the physiological characteristics of the arch, complete flat bottom design does not protect the arch. On the contrary, a foot arch and a heel with a suitable height can increase the stability of flat shoes. The selection of shoes must pay attention to the design of sole. Too thick, too heavy, too light, and excellent are not in line with human physiology. Choosing suitable height, elastic shoes and suitable materials is suitable for long-term walking.
