(two) related terms of shoe upper

Counter - heel and heel. It can often be seen in the heel of a basketball shoe, providing additional support for the root of the foot. It is usually hidden between the shoe lining and the exterior materials, but the heels of some sneakers are designed outside.

Dynamic-fit sleeve - Dynamic-fit shoe covers. Nike a kind of shoe interior technology, the synthetic elastic fiber shoe sleeve of this seamless line can completely wrap the feet and provide better comfort and support.

(three) terminology for midsole and outsole

AdiPRENE -- Adidas's shock absorption technology. AdiPRENE is an elastic material designed to provide wearers with shock absorption when walking. It is usually used in the heel part of shoes.

AdiPRENE+a -- didAs's shock absorption technology. AdiPRENE + is similar to adiPRENE technology. The difference is that adiPRENE + is more flexible, and is generally designed to provide better forehand power.

Air - air cushion. Nike's shock absorption technology is now being applied to many different types of shoes. Air technology was invented by Marion Frank Rudy in 1984. Its technical principle is to compress compressed gas into the "package" made of polyYaan ester material, and the volume of these gas molecules is too large to enable them to pass through the poly Yaan ester isolation layer. In 1997, Nike ended its technological monopoly on Air, allowing competitors to produce shoes based on Air shock absorption technology, which is why we can see more different brands of air cushion sneakers in the market now.

Air, Encapsulated - compressed air cushion. The air cushion is compressed into the midsole of the shoe and can not be seen from the outsole.

Air, Max - high pressure way, special gas is poured into a tough synthetic rubber, the air cushion pressure is composed of different pressure chambers by 5psi.10psi.20psi.25psi, and more shock absorption performance. And usually Max Air based sneakers are relatively few in midsole interlayer, which is based on foam rubber damping materials, so it can properly reduce the weight of the shoes. Max Air is usually visible and is usually used in the front and rear parts of shoes.

Air, Total - the whole foot air cushion. It is an upgraded version of Max Air. It is made up of several different cushions. It provides safer and more comfortable protection and shock avoidance for athletes.

Air, Tuned - evolved from Max Air, consists of a group of hemispheres made of polyYaan based materials which are placed opposite to each other to provide additional shock absorption performance of sports shoes in specific areas.

Air, Zoom, an advanced shock absorption system based on Nike Air technology, provides faster response and cushioning performance closer to the ground. The Zoom Air-sole unit is made up of two layers of high-density nylon elastic fiber three-dimensional fabric sealed by the Yaan ester gasbag. Such a combination makes the elastic fiber react quickly when the air cushion is subjected to strong impact, and the pressure will disperse rapidly. This effect is similar to that of trampoline. Most of Zoom Air is often placed in the front part of basketball shoes, but a few times are used in the heel part.

DMX - Reebok's shock absorption technology, a technology combining air cushion shock absorption technology with gas flow system. The mobility of gas in air cushion is realized by several interconnected gas chambers. When subjected to impact, the gas will flow rapidly from the compressed air chamber to other gas chambers, and then return quickly, so as to achieve the purpose of cushioning.

Ethylene Vinyl Acetate (EVA) - vinyl acetate fiber. Light and flexible chemical synthetic substances. Most manufacturers use EVA material in the manufacturing of the midsole of shoes.

Flex grooves - curved grooves. The front palm is used to raise the curvature of the front palm.

Herringbone - herringbone pattern. The texture of the tortuous pattern used in the outsole of the sports shoes can provide a good grasp of the terrain energy.

Harmonix - And 1 shock absorption technology, the principle is to use low pressure to charge gas into the encapsulated Yaan ester skeleton structure of the air bag. It is used to provide a higher level of rear impact protection with And 1 Springz geometry technology.

Outsole -- the outermost sole that touches the ground.

Phylon -- lightweight and flexible buffer material made from heated compressed EVA foam rubber. Phylon is a proprietary technology of Nike. It is usually used in the midsole of the forehand, but sometimes it is used in the midsole.

Polyurethane (PU) - poly Yaan ester. A high density durable material based on foam rubber which is often used in the midsole of the back.

Springz Geometry - a dome type midfloor sandwich that is used to absorb impact force on the rear heel and And 1 Harmonix damping system. When there is a downward force, it will force the dome to deform and absorb the impact force. When the downward force is disappearing, it will soon return to its original state.

Shank -- shoe core gasket. Hard bars are usually inserted into the sole and bottom of the palm part by carbon fiber, thermoplastics polyurethane rubber, wood fire and smooth leather. The shoe core gasket of basketball shoes provides extra palm support and keeps the front and rear palms consistent.

SHOX - Nike's shock absorption technology is a cylindrical special motion component made of high density polyYaan ester foam rubber. In the application of basketball shoes, its special design structure can provide excellent stability and high level impact protection.

TORSION -- torsion system. Adidas's stability technology is designed to provide natural and smooth rotation between the front and rear legs while providing palm support.

Sample sample shoes, a shoe made of a proposed proposal, has been produced for decision making purposes, producing only about forty pairs. That is to say, the shoes made for decision making and reference are 9 yards for men and 7 yards for women. They are only used within the company, producing only forty pairs at most, so in a sense, they are limited, and most of them are hand-made, some of which are not going to be listed, or the "wrong edition", so they are of great value to the market. In addition, Sample also represents shoes specially produced for players, with special markings representing the players.

SC Sports Classic classic sports shoes, that is, some once raised shoes and then re issued the name.

Prototype shoes for trial production: shoes that are produced in a very small quantity and are only worn by individuals or organizations. They will not be sold publicly.

NDS Nearly Deadstock, a brand new item, means that the shoes have not been worn out before, but only wear them in the test shoes.
Condition refers to the perfect condition of a pair of second-hand shoes, commonly seen on second-hand auction sites, of which 1 represents a better state with a minimum of 5.

Air, Max Air & Max 360:

The first thing to do is 3/4 Air-sole, which can be regarded as an ancient NIKE air cushion.

The use of Air Force 1 is the air cushion and is embedded in the PU bottom to form together.

(although the shape of the AF1 rear heel chamber is different from this one...)

Gas has the property of isotropic expansion.

Instead of many air cushions like leather shoes nowadays, it's actually just PU foam.

The air cushion must be evenly distributed in the sole of the foot.

So, like many small holes seen in the photo, the purpose is to divide it into many connected small chambers.

The whole can still maintain a relatively flat state, otherwise it will be bulged like balloons.

Surface small bump... In AF1, AJ1~AJ9 is the air cushion finished in PU foam bottom bottom together solidification.

In AJ10, AJ11, Nu'Retro AJ2, etc., we reserve a lower plane on the bottom surface of Phylon.

Air-sole is embedded and glued... After wearing for a period of time, it often causes friction and creaks.

This is less likely to happen in shoes before AJ10.

The max era is coming! Max technology will increase the volume of the air cushion in order to gain greater buffering capacity.

Max 180 uses the material at the bottom of the max air area to expand the visual effect to 180 degrees around the two sides.

Max 270 extends the territory of max air to the location that connects to the heel.

The volume of the air cushion is also significantly larger than that of Max 180.

The midsole foaming material is separated from the air cushion by the air cushion.

Its lateral stability and supporting force are also of great help.

In this sports shoes market, we are developing by leaps and bounds in the middle of the'90.

The study found that the rear heel is the place where jogging is the first to hit the ground with the highest friction probability.

Therefore, an independent low pressure chamber (5 psi) * is placed behind the heel in air max'95 * the rest is 20 or 25 psi.

The first landing area has the softer cushioning for the first time. There is a marked improvement in comfort.

And in the coming year, it is further confirmed that this region should be located posterolateral to the heel.

For example, the max air used in air max'96 has been adopted so far.

* Note: psi, pound per square inch, pressure per square inch (unit weight); 1 ATM (atmospheric pressure) = 14.7 PSI

This is the max air used for air max'99.

The front foot is not like a tubular gas chamber arranged parallel to air max'97, but uses a design similar to that of a basketball shoe, which is conducive to the front and rear bending of the baseboard.

The rear heel and the lower side are all low pressure airbags, such as the low pressure airbags, the outer ring high pressure main chamber, and the form of max2 in the form of Max'96.

But after that, the max air, which is used in air max 2003, is still used in the main form of air max'97.

Max 360!!!

The middle foaming material is subjected to repeated oppression for a long time. Its microstructure will be destroyed gradually, and become flat and collapse.
Therefore, there will be a marked decline in the ability of shock absorption and elasticity after a period of time.

Of course, in the past, air cushions embedded in foam bottom can increase the shock absorbers.

But it does not change the fact that it will be affected (though the impact is not so obvious).

But the main reason is the ideal realization of the 100% foot air cushion.

The slogan: RUN ON AIR in the advertisement is quite apt to depict this ultimate dream.

In terms of exterior structure, max 360 is like the combination of Air-sole, max air and cage structure.

Completely abandon the bottom foaming material and maintain a large gas chamber to achieve this ideal. The TPU structure is the answer to how to maintain stability.

The whole TPU structure constitutes the main skeleton supporting max 360, including the heel and the most edge of the whole.

The "column" that separates the gas chambers is the same structure as the concave design purpose of the Air-sole forefoot...

There are four small pieces of structure that are perpendicular to the bottom of the heel and the outer side of the forefoot.

Objective to provide the three-dimensional support force and stability between nearby columns.

The two feet of the forefoot are deep and concave. The design at the beginning takes into account the more flexible bending.

In basketball shoes, the outer sole part of the front sole has an upward extension to meet the lateral stability needs of the basketball.

The TPU structure of max 360 is integrated with the plastic film of air cushion.

On behalf of NIKE, the technology of air cushion is even higher. It feels that it will throw further into other industries.

After marveling at its superb technology, the most important thing is wearing sense.

The main body of the shoe is bonded to the TPU structure with the outer edge. The upper part of the air cushion is the insole and then the insole.

The feeling of wearing max air in the past is obviously the mixture of foam bottom and air cushion.

Only through max 360 can we realize the extreme comfort and excellent elastic experience of RUN ON AIR and still maintain good stability.

Previous air max 2003,'97,'95 and so on.

Air cushion technology seems to have reached an ultimate goal now. It seems that there is little room for development.

But there is often a surprising NIKE... Who knows if they will come up with something new to frighten us?
