According to the principles of justice who advocate who is the burden of proof, so far, however, did not give Nike Air shoes can reduce the damage enhance the protection of reliable evidence. And Beijing is the body of the Institute of Mechanics, through long-term study has found the air-cushion shoes security issue in accordance with the theory.

nike shoeswith air cushion between the ankle sprain is not difficult to explain necessarily linked." Zheng Qingsheng reporter for the construction: ankle sprain commonly known as "Wei feet." Generally speaking, the legs of the lateral force usually higher than that inside the (people's shoes were always the first to wear lateral This is the reason), the campaign on easy for the foot inward and overturned while Wei feet. Increasing the thickness of the air-cushion heel height, the feeling of the ankle joint becomes slow, the thick air cushion, inside overturned and the possibility of greater potential energy, and the more serious injury, with high heels truth easily Wei Feet are the same.

Stability can not cushion the formation of the "flap" effect, increasing the risk of Wei feet. Feet of the lateral to, the impact of making a lateral compression air-cushion thickness decreased, the corresponding increase in medial thickness, the entire soles moment to form a slant and aggravate the imbalance foot to the ankle joint inward and overturned. The thick air cushion is, "flap" the stronger the effect.

Not just at the foot movement poses a potential threat, actually air-cushion shoes also affect human health and development. Zheng Qingsheng pointed out that the first impact on the heel height of foot health. A typical high heels is triggered by a series of foot disease, such as the great toe valgus, Zhijian neuroma, Pingzu症等, the extent of damage and the size is proportional to the height of heel. Shoes and more is in the air cushion with, and wear shoes in the foot with the negative development.

"Heels height of the spine also have indirect effects." Zheng Qingsheng, who is a mechanical whole, if people compare a building, then the shoe is the foundation of this building. With the increase in heel height, the focus gradually moved forward, spine bending also gradually increasing, the lumbar and cervical force more and more concentrated, natural form of chronic injury, this injury eventually led to the accumulation of low back pain and cervical spondylosis Occurred. The role of the same principle and high heels, can be caused by the foot of the change and the curved spine, with the high heels of the only differences, but not completely qualitative difference.

It was proposed: Genxie in the foot can become the force before and after the average, thus beneficial to health. "It looks like scientific knowledge, but as long as a little analysis, is easy to see that it is a pure layman's low-level error." Zheng Qingsheng again reveals one of the breached. "Foot structure is clearly uneven, both the bones or muscles and ligaments, the former are Yuanxun Yu rear foot, the load-bearing capacity of the natural differences are quite large, so that before and after the foot to bear the same token there is no pressure. It must be Will damage weak position, which is more than a foot disease in the foot before the root causes. 'Uniform' does not mean that the 'reasonable' and will confuse the two is a conceptual mistake, no scientific basis. Furthermore, the people have their own campaign of shock Harmless, in the scientific community is the conclusion of Genxie ease the shock of the health significance is untenable. In fact, when people wear Ping Dixie state of the mechanical and barefoot basically the same, is the most natural, most of nature State, in line with the human body structure and mechanics of movement. 補正下着"

Zheng Qingsheng said at the same time by the State Sport General Administration of Sports Science Institute Jing Hao Wei, an associate professor of center-affirmed.
