Seminar On Shoemaking - Cushioning Technology

First of all, we should understand that the technology of earthquake mitigation belongs to the science and technology field.

The sole is divided into two parts. The part directly touching the ground is the outsole, the rubber sole. The middle part between the insole and the sole is the middle sole.

The mission of midsole is to reflect the cushioning performance of sneakers, and almost all of them are attached to this part.

There are two parts of the sole of the regular sneakers, and the foam rubber as a carrier is what we call PHYLON and EVA.

In fact, there is no essential difference between them. They are both foamed rubber. They are identical in structure and material.

Only EVA is more thorough than PHYLON foaming, more advanced technology, smaller density, lighter weight, better elasticity and softer.

Their structure is like sponge, many small holes, that is, the so-called "bubble".

Their raw materials are no different from other rubbers, they are raw rubber.

Only the different processing methods give them special physical characteristics.

If you don't believe you can burn it with fire, it's very hard to cool down after burning.

Foaming rubber is the earliest technology for modern sports shoes.

Before the birth of AF1, all the sneakers were filled with foam rubber.

Until the birth of special cushioning technology such as air cushion, foam rubber was relegated to the second seat, and became the support and support for embedding special shock mitigation technology unit.

For example, the general ZOOM AIR is embedded in the corresponding cushioning position of foam rubber, that is, the position of heel and forehand.

These two parts are the most stressed parts of the body, especially the heels.

When we jump off the ground, we first use the front foot to touch the ground, and the arch first cushioning. Then the heel hits the ground, and most of the impact is borne by it.

If there are no cushioning devices at our feet, this part of the tremendous impact will be pmitted from the heel to the upper side.

The first is your knee joint, then your spine, then your brain will oscillate through your teeth.

Professional players wear silicone braces and are not designed to protect their front teeth. Another important function is to cushion the destructive power of this part of the brain.

This is the fundamental reason for the existence of mitigation technology, that is, protection.

Protect your joints, protect your spine, protect your brain.

Of course, first of all, protect your feet.

The following is the focus of this lesson, the special seismic unit that you are most concerned about.

As mentioned above, foamed rubber has become a material rather than a technology.

Therefore, we do not need to use the word "special" to define seismic mitigation units.

And future trends show that foamed rubber will be completely eliminated.

AIR MAX 360 technology is an attempt in this direction. The whole middle floor is air cushion, without foaming rubber, and directly underneath the bottom. Clarify here, I think the whole palm SHOX can not be considered in this development direction.

Because the SHOX column itself is still foamed rubber, but it is just another rubber column that emphasizes resilience.

In fact, from the point of view of physics, all mitigation technologies are the buffering principles of physical deformation.

Air cushion, honeycomb, DMX, oil bag, cushioning rubber, SHOX, A3 are no exception.

There is no exception, which is determined by the laws of physics.

Unless the development of Maglev or jet propulsion technology in the future, this is not what we can do under existing technology.

Or more daring to speculate, directly inventing the anti gravity technology sports shoes, OK, wear a pair of shoes and put on the spacesuit, you can go to outer space.

Far away, I mean that the existing mitigation technology can not be categorized strictly.

Let me talk about it one by one.

Compared with various mitigation technologies, air cushioning technology is undoubtedly the most important in terms of success and influence. Air cushion technology brands include Nike, Reebok, CONVERSE, AND1, PUMA, SPALDING and so on.

Since Nike released the exclusive technology of air cushion technology, many brands have developed their cushioning cushioning technology, but the most successful is Nike itself.

Nike's air cushion technology has been developed for more than 20 years with various forms, and the earliest one is AIR SOLE.

As the foundation of air cushion technology, AIR SOLE has developed many forms after years of development: the whole palm, half palm and so on.

Then there is the AIR MAX air cushion, that is, the large capacity air cushion.

MAX air cushion also has many forms, single air chamber, multi chamber (MAX95), and TOTAL MAX (MAX2003).

Later, there was a special MAX AIR called TUND AIR.

The rubber support with hemispherical body inside the air cushion is divided into multi air chambers.

The pressure inside and outside the air chamber is also different. The lateral pressure is strong, which is 25 OPSI, highlighting the supporting protection, preventing the air cushion from being too soft, resulting in ankle sprain.

The inner chamber is 5 OPSI, which is mainly responsible for slow shock.

Such an excellent air cushion has not been widely used. In basketball shoes, the most representative one is Garnett's Air Garnett 3.

At the same time, the most successful form of air cushion ZOOM AIR was born.

A pair of ZOOM AIR basketball shoes in history should be AIR ZOOM FLIGHT 95? Just repeated, oh, commonly known as fly compound eyes, I personally do not like this design style very much, maybe I am old.

Speaking of ZOOM AIR, are you all a little excited?

Here I will spend more space to introduce the most successful air cushion in history.

In general, ZOOM AIR is also divided into full palm and half palm.

At the same time, half palm also has the distinction between large capacity and small capacity.

AJ18 double ZOOM air cushion on the back palm, the upper layer is the small capacity half palm ZOOM, the next layer is the whole palm ZOOM.

Of course, the whole palm ZOOM is first applied to AJ12, though not very successful.

(the revised AJ12 improved the design flaws in the first year, with beautiful feet).

The 2K4 used is a large capacity half palm ZOOM. Those who have removed the shoes know how thick the back ZOOM is, and how small the front palm is.

ZOOM AIR can be made into almost any shape, so its shape is very large.

The most intuitionistic is AJ21 and AJ22's replaceable ZOOM unit, the other is the multi chamber and so on.

By the way, there is another CAGE ZOOM, which is the outer one covered with a cage.

That's the thickest ZOOM. The shoes represent the Air Zoom Drive AF that Nash has passed through. The air cushion is really very soft.

Similarly, there are LBJ2 and LBJ3 PEPAX ZOOM.

In fact, the official plation of ZOOM AIR is called the "impact air cushion".

The original design idea is to provide stronger resilience, which makes the athlete's foot closer to the ground with thinner thickness, rather than emphasizing the effect of slow motion.

In the two aspects of rebound and thickness, ZOOM AIR has successfully implemented the designer's intention.

There is no need to say more about anti elasticity. The basketball shoes that successfully use ZOOM AIR in the forehand can be enumerate.

And close to the ground function, the latest two shoes is the best interpretation of this feature: a pair of ZK2, a pair of ZOOM BB.

But in fact, what ZOOM really attracts us is its cushioning function.

Both the half palm and the full palm ZOOM provide gentle and average cushioning for us, and bring unparalleled comfort effect at the same time.

ZOOM's soft and full air cushion can match it, that is, MAX AIR.

But not all MAX AIR can provide this extreme cushioning foot feel.

I think only the MAX AIR with 270 degrees opening the back of the palm and the MAX AIR of the back palm used in the PENNY series can achieve this effect.

But TOTAL MAX AIR, which seems to want to maximize the cushioning effect, failed to achieve this design goal.

The reason is that TOTAL MAX AIR can not achieve this effect by single chamber and unsupported structure.

TOTAL MAX AIR is actually a combination of many small air cushions, and when the air cushion is inlaid on sole, it is necessary to cast hard rubber foam to bury it, so as to ensure its stability.

But this has led to a disadvantage. The supporting columns formed by the interspace between the foam rubber in each air chamber greatly restrict the deformation range of the air cushion.

The air cushion can not play the cushioning function completely. When the air cushion gets a little bit of pressure, the top to the foot is not the air cushion, but the hard foam rubber, that is PHYLON.. So TOTAL MAX AIR is not as soft as it looks, it is more visual and psychological to meet us.

ZOOM AIR has completely solved these two bottlenecks.

Unlike traditional air cushions, the fine filament inside ZOOM does not limit the extent of air cushion sag, but is used to prevent air cushion from overexpansion.

If they did not pull the outer layer of the two layer up and down the ZOOM air cushion, the ZOOM air cushion would expand into a sphere and burst quickly.

It can be said that the technology of fiber pulling has made the air cushion technology achieve a qualitative leap in performance.

Moreover, when the designer connects the two pieces of ZOOM in the front and rear half of the palm, the whole palm ZOOM AIR has another powerful function -- the energy pmission effect of the heel and forefoot formed by the gas flow.

That is to say, it will instantly change the impact of your defensive landing to the explosive force of counterattack.

This function immediately dwarfs RBK's DMX airbag.

Because DMX is too fragile.

Speaking of durability, ZOOM AIR is also better than Nike's other forms of air cushion.

The outcome of MAX AIR burst is almost inevitable, and ZOOM AIR rarely happens.

Moreover, ZOOM AIR can be embedded in EVA without sacrificing the cushioning and comfortableness.

In this way, ZOOM AIR has more protection, and this layer protects the air from oxidation by air, making ZOOM AIR more durable.

MAX AIR 360 technology has also achieved good results in cushioning performance, but it is still not as thorough as ZOOM. It always needs bracing.

And MAX AIR 360 is like DMX's short life.

Therefore, the performance of ZOOM AIR meets the requirements of earthquake mitigation, elasticity, light weight, comfort and durability.

ZOOM AIR is currently the best form of air cushion technology.

NIKE's air cushioning technology says that, then briefly talk about other brands of air cushion technology.

In terms of air cushion technology, Reebok is undoubtedly playing the role of millennial second.

In fact, Reebok is recognized as a pioneer in the development of sports shoes technology.

Many modern basketball shoes technology is first developed and used by Reebok.

For example, CARBON PLAT is Reebok's first use.

But Reebok's development of technology for shoes and shoes is like a blind bear breaking a spike.

They invented all kinds of technology, but none of them could make it.

This is just too unreasonable. It makes people laugh and cry.

Reebok looks as if it is neurotic, and it is unreasonable to waste their own research results, specializing in making clothes for others.

I didn't fall in love either. After all, people had been bought.

DMX is undoubtedly RBK's air cushion, but AI 4 makes this seemingly perfect air cushion form a smelly year.

Who wants to spend 1000 yuan on a pair of shoes that can only wear for three months?

We know all the details, not much.

Focusing on the famous HALEX honeycomb air cushion, the structure of this air cushion has the same effect as that of ZOOM.

But beehives are essentially not called air cushions, because the real ones are not the gases inside, but the hexagonal honeycomb supports.

This is why the honeycomb air cushion ruptures and leaks, and its damping effect is not affected.

Therefore, the honeycomb air cushion is essentially a pseudo air cushion form.

But because of its outstanding stability and good cushioning effect, it has been used as the main shock mitigation technology by many brands.

PUMA and SPALDING are also successful brands using honeycomb air cushions.

In spite of this, the structure of the honeycomb air cushion determines that its performance is not perfect, and it can always be a marginal role.

But CONVERSE's helium air cushion, oil bag technology has just changed into fillings, and there is nothing new in design.

AND1's air cushion is a joke. It's a little joke. It's not worth mentioning.

In the era of surging clouds twenty years ago, the core content of the brand competition of sports shoes is technology.

The core of technology competition is slow vibration technology.

Finally, the focus of the technology competition is focused on air cushion technology.

It is no exaggeration to say that the quality of the air cushion determines the success or failure of the brand.

The so-called Cheng AIR also defeated AIR, Nike succeeded, and other brands failed.

As for ADIDAS, it is a clear choice. It chose to give up.

So it still has the qualifications of a second person. After all, the sport on the grass does not need any mitigation technology.

In other sports fields, after struggling for several rounds, it also failed obviously, especially basketball shoes.

Although ADIDAS chose to avoid it.
