Lining: The Secret Of The Innovation Of Running Shoes Materials

With "super light" and Shock absorption technology In evolution, Lining helped sports enthusiasts improve their running experience.

Unconsciously, the heat of running has sprang up in large and medium-sized cities in China. Under the shade of city parks, people who run and keep fit can be seen everywhere in the morning and evening. The Beijing international marathon will soon be opened soon after the end of the marathon in Guangzhou and Beijing. According to statistics, 10 years ago, the number of Marathon games in the whole country was only 10. In 2012, the marathon race, which was certified by the China Association of Tian Chang, has reached 34. This year, it is expected to break through 50 games.

Famous enterprises are unwilling to be lonely and push their running in succession. In 2013, Lining, the industry leading sports brand, launched the 10 km road race League, which lasted for 5 months, spanning 8 cities such as Shenzhen, Xi'an, Shanghai, Qingdao, Changchun, Changsha, Wuhan and Chongqing. More than 30000 runners participated in the competition and accumulated a lot of popularity among the runners.

Urban people want to run and run. They are light, smart and can run with shock absorption and protection. shoes Essential. Nowadays, a pair of good shoes not only test the quality, but also the technical content. The following is a case of Li Ning Co's ultra light series running shoes and ring arch running shoes.

Reuse of lightweight materials

According to research, the weight of running shoes is reduced by 1 grams per kilometre, and the weight of running shoes can be reduced by 560 grams per kilometer. The ultra light running shoes series is the longest and most abundant product line developed by Lining. It has lasted for 9 years and has evolved to the tenth generation in 2013. In the domestic running shoes equipment, the "light" of this series is quite convincing.

Shoes are light, first in materials. Lining Designer The team constantly contrasted the selection and the shoe material changed several times. The basic supporting material widely used in shoemaking industry is TPU, TPU has the characteristics of wear-resisting, flexible, easy to process and so on. It is generally the sole choice of sole. However, the density of TPU is about 1.10 to 1.25g/cm3, slightly heavier than water. Starting from the "ultra light seven generation", Lining reduced the use of TPU, but used different density of light fiber collocation. At the same time, the whole body used seamless hot paste technology to reduce the use of needles, in order to achieve a better weight loss effect.

After the "ultra light eight generation", Lining introduced Monomesh breathing net cloth on the basis of seamless technology, and the MonoMesh net cloth surface is thin like spinning, which is considered to be the best material for making lightweight shoe upper. In the "ultra light eight generation", Lining also developed the exclusive C-feet shoe last and COMFORIDE insoles based on Chinese foot data and improved the comfort of running shoes.

After two years of research and development, Lining's design team has a new understanding of the crisp MonoMesh net cloth. The texture of MonoMesh material is thin, but if we want to enhance the overall package property of the running shoes, it will be tightly bonded with the feet, which will easily lead to the weakening of the air circulation inside the shoes. Thus, after repeated trials, the "ultra light ten generation" introduced in 2013 has made new changes. The design team adopted the new processing of "sandwich net cloth" covering the MonoMesh net cloth, making the upper part of the shoe have a high elastic and reliable support while making full use of the obvious line structure of the Sanming net cloth, supporting the thin MonoMesh like the cicada, so as to achieve the effect of two breathable and breathable.

To ensure the stability of running shoes in the vertical movement, the Lining design team has added the new material Carbon Fiber, which is highly respected nowadays. Carbon fiber has the characteristics of light weight and high anti-seismic strength. At the same time, it also has the characteristics of high temperature resistance, friction resistance and corrosion resistance. It has been used in the manufacture of high-precision and sophisticated products such as aircraft, rockets, industrial robots (43.050, 1.11, 2.65%), and was once a key material with political sensitivity. Historically, it has been included in the list of embargo by the Paris Co ordinating Committee (COCOM).

In the ultra light ten generation, the rigid and flexible carbon fiber is vertically attached to the middle of the shoe body and interlaced with the transverse TPU protection belt, forming a strong "ten" word stabilization system, firmly fixing the feet in the movement, and effectively resisting the high strength friction on the basis of keeping comfort. This design enables the whole shoe upper to provide effective protection and support with a lightweight and simple structure to fit the feet, allowing runners to feel comfortable and comfortable while experiencing light running experience.

"In ancient times, people often pulled the rope into" ten "shape for packaging, they thought it was the simplest and the most effective method, the most common is the temporary packaging of Chinese herbal medicine. According to Lining designer Sun Jingyi, the "ten" word stabilization system just comes from the implantation of Chinese cultural elements.

In addition, the "ultra light ten generation" has also extensively used and reorganized the classic design. Texture of material For example, the classic FormEVAlite technology platform is equipped with a newly upgraded Bounse Plus technology, so that the weight of running sole is reduced again. The synthesis of the above technology makes the product's sole shoes weigh only 212 grams, and has entered another "light" realm.

The secret of shock absorption

For runners, it is an irreplaceable pleasure to devote themselves to full play. However, long-distance running inevitably brings impact on human muscles and bones, especially at the ankles and knee joints. It is very easy to cause damage. Damping is an important consideration in the design of running shoes.

As early as 2006, Lining released the "Lining bow" shock absorption system, which is composed of three parts: Arch, Tensile and PU. The system is dominated by Li Ning Co, and is the first domestic R & D technology platform for sports shoes. Dr. Frederick of Exeter Research of the United States has provided the original idea of Lining bow shock absorption technology, that is, to build a unique combination structure of arch bridge and tie bar, and use the principle of "arch compression deformation to effectively relieve pressure". Interestingly, Frederick later recalled that the inspiration came from China's Zhaozhou Bridge.

At the beginning of 2013, Lining launched a new generation of bow running shoes, carrying a new upgraded bow technology. While retaining the unique damping principle of the arch and string structure of the Lining bow technology platform, it also creatively integrated the way of material damping: the PU ball with excellent damping performance with TPU film, and stabilized, reinforced and molded on the outermost layer with rubber strips, forming a new arch and string structure, and thoroughly reconstructing the loop unit module.

The Li Ning Co will flexibly combine the miniature bow ring shock absorber module with the smaller size, and place it in the most concentrated area of the sole heel. Based on the in-depth study of the running track, it will adjust the detail position to achieve the shock absorption and protection for the key parts of the foot during long distance running.

Specifically, in running, when people are running, the force of the landing is concentrated on the heel, and it moves forward with the pace, and the pressure moves forward from the hind foot. As a result, the Li Ning Co has placed two independent ring arch damping units on the outside side of the sole of the shoe longitudinally, coinciding with the main force points of the runner's feet, and consistent with the running track, which can accurately resolve the impact force generated on the ground when the feet are landing. At the same time, it provides a reverse rebound force, effectively guiding the running track, controlling the inside and outside of the foot, reducing the shock absorption effect and improving the running experience.

In fact, in the bow technology. R & D process In addition, Li Ning Co has invited professional players to participate in the try on experience and draw feedback from professional players. After 4 big bottom reforms and nearly 20 fine-tuning, the players are improving. However, technological progress is endless and the same is true for shock absorption.

It can be said that the evolution of a pair of good shoes is like a technical marathon.
