The Design Principle Of Soles Shock Absorption Technology Is Widely Disclosed.

< p > the most commonly used method is cushioning vibrating base or < a href= "http://www.91se91.com/news/index_x.asp" > substrate < /a >.

This material is added to the sole of the shoe, and the middle sole itself plays a major role in buffering.

The sole of most running shoes is made of EVA, and occasionally rubber or PU is added to enhance durability.

EVA material has good application performance. It can produce different hardness States and meet different compression requirements.

< /p >

< p > EVA can also be blended with rubber to make a better elastic middle sole. Asics, Brooks, New Balance, Saucony and other brands all use a variety of mixed recipes.

Mizuno has a polymer called AP, which performs better than EVA. The running shoes rely on the AP midsole to meet all the shock absorption requirements.

< /p >

< p > Asics uses SpEVA mixed material to make Strobel structure less than a href= "http://www.91se91.com/news/index_x.asp" > shoes < /a > the complete insole, this is a very soft sole, giving consumers a good "try on" feeling.

Why can't this idea expand to non sports shoes when different hardness is used in different < a href= "http://www.91se91.com/news/index_x.asp > shoes > /a > initial flexibility" try on "will be a strong selling point for comfortable shoes.

Mechanical shock absorption is also used. The structure includes cantilevers, wave plates, mechanical springs and other profound but popular concepts. There are many ways to improve performance but focus on sales promotion. When the sole is very thick, the shoes are either too large or too mechanized.

< /p >

< p > the insoles of factory shoes are usually easy to manufacture for reasons of cost reduction, while the after-sale market has all kinds of complex insoles. Shoes suppliers, such as Rogers and Jones & Vining, provide flat or molded cellular foam for almost any type of shoes.

They provide simpler and more flexible means of shock absorption for manufacturers who lack the number of sports shoes.

< /p >

< p > < strong > the practice of brand sports shoes < /strong > < /p >

A shoe of < p > Adidas uses sophisticated computer operation mechanical system, highly intelligent but not suitable for other < a href= "http://www.91se91.com/news/index_x.asp" > footwear < /a >.

< /p >

< p > Asics also used gel layer, as long as enough sole thickness, the effect is very good.

It feels like a soft elastic body under the feet, which acts as a good shock absorber.

The suitable size of the closed gel pack forms a shock proof layer under the metatarsal part, and the SpEVA Strobel inner bottom has better damping effect.

< /p >

< p > Avia at the same time, the mechanical and material structure is applied to the cantilevered structure with strong function on the new shoes Ecto-Cantilever, which has better shock absorption function and may be used in hiking boots.

The company cushioning structure is very effective by putting its shock absorber < a href= "http://www.91se91.com/news/index_x.asp" > material < /a > Dura-Ryd to the front and rear heel parts.

< /p >

< p > Brooks adopts Hydroflow (liquid flow). It consists of a viscous material bag filled with room temperature and several convenient liquids to flow through shock resistant duct.

The cushioning bag at the heel is not only shockproof, but also has a positive stabilizing effect.

This structure is also suitable for hiking boots.

< /p >

< p > Fila also combines mechanical damping and material damping in two forms. A mobile structure supports the foot to form a buffer and a slight downward control, or form a more effective motion control according to the shoe shape.

The supporting structure is designed to be convex and concave to eliminate impact. Similarly, this intelligent design is not suitable for other footwear.

Asics Gel Sciatic shows its sole cushioning aseismic integrated system < /p >

< p > Mizuno has several good technologies. VS1 damping material is a good shockproof base material, and its deformation resistance to feet is better than other materials.

It is used in two parts of heel and forefoot. The new advanced polymer terminal material is lighter, more shockproof and over EVA. The overall shockproof effect is excellent but not fancy.

< /p >

< p > New Balance does not pursue innovation very much. It mainly relies on material < a href= "http://www.91se91.com/news/index_x.asp" > shock absorption < /a >.

The biggest improvement is to use a soft sponge material called Abzorb to integrate two materials into the bottom.

The former part uses a more advanced silicon based material to form a good impact resistance.

It also uses a mixture of intermediate materials similar to SpEVA, which is obviously suitable for other shoe types.

The success of < p > Nike over the years has been mainly attributed to the Air (air) structure. After the publication of the original Tailwind in 1978, the structure has been continuously developed.

After the patent expired in the late 1990s, Nike introduced Shox, a top-level mechanical and material composite structure.

The top tier is actually a lot of foam filled plastic bars, placed between polyethylene (PE) boards, improving performance, but also serves as a marketing strategy.

< /p >

< p > Pearl Izumi is a new company that combines mechanical Syncroframe with damping material called Sydex.

Syncroframe, like the shoe's guiding structure, is designed to support the soles of the feet and buffer vibrations.

The plastic frame is embedded in the rear and front parts of the middle sole, and the additional Sydex is very similar to the existing damping material.

If applied properly, the support concept can provide useful support for other shoe types under foot pressure.

< p > Puma has launched several major innovations in a timely manner. It is now stepping up the development of duoCELL foam less novelty less than a href= "http://www.91se91.com/news/index_x.asp" technology < /a >, a mechanical and material two in one form of shock absorption, with considerable prospects.

Its shape is five angle plastic small capsule, hollow, wall and top hard, forming impact resistant unit structure.

DuoCELL consists of a bottom unit and a large number of stacked small units. The working principle is similar to that of the piston, and the small unit shifts the force of absorption to the large unit at the bottom.

The unit structure takes the place of the usual midsole material and makes it a completely non foaming method.

< /p >

The DMX foam capsule unit of < p > Reebok has always been the most important material for its pride. DMX Walk walking shoes are still used. It is a completely different air cavity structure. When the shoes are on the floor, the compressed air flows from the back of the foot to the front part of the foot, lifting the feet back to the back foot.

This concept is not new, and Clarks has adopted similar designs for many years.

< /p >

< p > Spiro midsole display wave elastic mechanical shock absorber system Saucony has an unusual structure. GRID (grid method) is filling a small box into the middle bottom of the heel, and its outer frame is fastened by one rope from one side to the other side, like a tiny tennis racket placed under the heel to catch the impact of tennis.

This method may not be suitable for extreme situations such as galloping, but the application is basically successful and suitable for other footwear.

< /p >

< p > Swiss Masai is designed to change the whole body posture, a href= "http://www.91se91.com/news/index_x.asp" > shoes < /a > feeling slightly different. For the first time, shoes need adjustment period.

Although the technical concept of shoes is a neutral plane, a soft wedge is placed under the heel and the foot is compressed when landing. This method is generally suitable for sports shoes.

< /p >

< p > < strong > conclusion: < /strong > over the years, many seismic design methods and energy rebound designs have been tried. Many of the extreme and strange concepts fail to withstand the test of time, and the long used method is damping materials.

It is easier to switch to other footwear because it can generate many derived methods.

The continuous progress of polymer engineering also means that there is no limit to the improvement of shock absorption methods.
