How can Air Force One tell the real from the fake?

First, the difference between shoe labels.

False: Fake barcode.

There are several thick and thin lines; The letter spacing of US, UK, EUR, and cm in the size bar is also unequal; The spacing between letters and numbers on a line of UPC code is not equal; The font looks blurry.

True: There are only two kinds of thick and thin lines in the true barcode; The letters of US, UK, EUR, and cm in the size bar are roughly equal; The letters and numbers of one line of UPC code are equally spaced; The font looks clear.

Second, the difference between shoebox fonts.

Fake: The font on the fake shoe box is blurred and the handwriting is incomplete.

Bottom Truth: The font of the Nike shoebox is natural in thickness, and the font size looks harmonious.

3. The difference between tongue logos.

Fake: The fake shoe part has an extra folded part, and the drill hole is not so thin.

True: The tongue label of the real shoe is wired, each hole is uniform and the feeling of the hole is more obvious; The corners are all intact;

Fourth, the difference between the flying wing logo.

Fake: The black part of the fake shoe is connected in many places, and the heart shape is not in the right position;

Bottom True: The logo of the flying wings of real shoes is concave and convex to the touch, all the black parts are not connected together, and the bottom of a heart-like shape is in the middle.

5. The difference between lychee cortex.

Fake: Since fake shoes are not necessarily cowhide shoes, you have to work hard to press out the texture;

Bottom Truth: Most of the leather used in the upper of the real shoe is cow leather.

Lychee peel is post-processing; The surface of lychee genuine cowhide has the characteristics of the original leather surface, the pores ** texture is clear, has good elasticity, and it is wrinkled when gently pressed by hand.

From this definition, we can quickly conclude that the definition domain d and the value range f(d) of the function f are exactly the value range and definition domain of the inverse function f-1, and the inverse function of f-1 is f

Air Force One's way of distinguishing the real from the fake is as follows:

1. The leather and the overall shoe type are fake using inferior leather on the market, which is easy to age, poor color and gloss, and the shoe assembly line is unprofessional and easy to deform. The true Nike Air Force 1 Classic Air Force Sneaker combines a premium upper, a sleeker fit and more refined detailing with an upper overlay for added support and durability on your feet.

2. The contrast of the tongue part, the fake one is made of two layers of inferior PU leather, the seam is rough, the car line is simple and easy to take off the line, the tongue is not thick and hard, which affects the wearing comfort, and the logo is not clear. The genuine leather is made of the first layer of leather, the workmanship of the outer leather and the inner cloth are finely stitched in place, and the tongue is the same as the counter, which is made of two pieces of leather spliced together.

3. Comparison of the sole logo. The fake sole air logo is an inferior plastic material, and the workmanship is very rough and not exquisite. The real sole air logo is made of high-precision plastic, the material is very full and thick, and the workmanship is exquisite and high-grade.

4. Comparison of the pattern of the sole mold. The fake sole is open to the mold, the star check pattern is rough and the rules are not perfect, the three-dimensional sense is poor, and the details determine everything. The real sole is open, the head and tail star check pattern is made, the workmanship is very fine, uniform and full, the rules are perfect and smooth, the three-dimensional sense is very good, and it provides enough durability, anti-slip and grip.

The authenticity of Air Force One can be distinguished from the logo and tongue, shoe label, overall quality, sole, and collar.

1. Logo and tongue.

Look at the shoes first look at the logo, generally on the logo will be very different, ** logo and tongue design is decent, exquisite workmanship, beautiful proportional design, and fake workmanship is rough, and even the exposure of the thread can be seen.

2. Shoe label. The Air Force One shoe label records the yardage, size, and place of origin, and the numbers are different from Arabic numerals, and the English of the origin column is also clearly spaced. If you look closely, you will see the gap, and generally fakes will not imitate it very similarly.

3. Overall quality.

The leather is soft, the quality is comfortable, the overall feel is delicate, and the upper body is also very light, while the fake leather is hard, the feel is rough, the leather is easy to age, and the overall wearing effect is not ideal.

4. Sole. Now the next step is to look at the comparison of the soles, although the soles we all wear on the feet, but there are often some differences, which are the conditions for our judgment, zoom in ** observation, we can see the difference in his subtle lines, and the size of the circle at the middle of the foot is a little different.

5. Shoe collar. Now let's take a look at the contrast of the collars, the leather of the collar is used similarly. There are slight differences in the uniformity and position of the vents, and the number of internal layers is the same. The white color is the same milky white as the mess, and the color difference is not obvious, so it is impossible to distinguish.

This way the foot is so bare that it won't be uncomfortable against the tongue (because the top half of the panel is slightly upturned), which is a truly premium production process.
