I don't know how much you know about the shoes you wear on your feet every day. Today, I'll take you to learn about it. Mastering these will help you choose shoes better in the future. The following mainly from four aspects to introduce.

1. upper:

The general term for the overall external parts of the shoe. It includes the shoe gall part, the front side part, the tongue, the transverse gall, the inner and outer parts of the middle part, the back cover part, the shoe mouth rolling strip part, and the elastic band part.

1. Shoe gall position:

The upper part of the shoe (I. e., the instep part) is a more conspicuous part of the upper part. Generally, the high-quality leather and style changes are reflected by the shoe gall.

2. Side parts of front side:

Located on both sides of the shoe gall, it is divided into the inner side and the outer side. Its bottom is glued into the sole, and the upper part is connected to the shoe gall, wrapping the front sides of the human foot. It bears the large squeezing pressure given by the human body, so it is a part that can reflect the comfort of shoes, and it is also a part that is prone to quality problems.

3. Tongue part:

The part connecting the shoe gall is the part where the shoe gall extends to the back of the foot. The function of the tongue lies in that on the one hand, it is close to the upper and back of the foot to make it not easy to fall off. On the other hand, it also plays a role in beautifying the upper of the shoe. Whether the appearance of the tongue is smooth and the appearance is correct reflects the overall spirit of the shoe.

4. Transverse bladder: A transverse decorative belt located at the connection between the tongue and the shoe bladder. The function is:

① cover the connecting seam between the shoe gall and the inclined body; ② the style change of the horizontal gall has the finishing touch to the shoe style; ③ further tighten the human foot to make it difficult to fall off.

5. Inner and outer waist position of middle side:

Located in the inner foot socket and outer foot socket of the human foot, it comfortably wraps the middle of the human foot, connects the front, back and bottom, and plays a connecting role.

6. Rear sleeve position:

Wrap the part of the human heel, it according to the shape of the human heel for the production of circular arc, on the one hand, cover the back heel so that it is not easy to fall off, on the other hand, can not be wrapped too tightly, in order to avoid "foot".

7, roll mouth strip:

It wraps the leather cut out of the exposed shoe mouth. On the one hand, it makes the leather not easy to be worn quickly. On the other hand, it prevents the shoe from extending and deforming. Generally, it is cut by wrapping the shoe mouth with thin skin cut into strips or wear-resistant PU, so it is called "wrapped mouth strip", commonly known as "rolled mouth strip".

8. Parts of elastic band:

The outer elastic and the inner elastic, the outer elastic is located on both sides of the tongue, and the inner elastic is located in the joint of the tongue and the shoe bladder in the shoe cavity. Its purpose is to increase the elasticity of the shoe, so that it is easy to wear and not easy to fall off.

2. in shoes:

The general term for the overall internal parts of shoes, which includes shoe lining, Hong Kong Bao and other accessories.

1. Shoe lining:

It is divided into the front part of the shoe, the middle part of the shoe and the back part of the shoe. They are all made of thin and breathable pigskin and sheepskin. There are also a few high-grade shoes that use cowhide. The front, middle and back parts are sewn according to the established specifications and sewn together with the upper material. Special attention should be paid to the use of reverse suede in the sewn sleeve, the purpose is to increase the friction between the heel and the shoe, which is not easy to fall off when walking.

2. Hong Kong Treasure:

Commonly known as "support head", it is made of a special material. When making shoes, it is placed between the inner and upper of the toe and the back cover of the shoe. The purpose is to support the toe and tail of the shoe so that it is not easy to deform, which is equivalent to the function of "shoulder lining" in a suit.

1. Outsole:

The parts of the sole that can be seen by the naked eye in direct contact with the ground are mainly made of rubber, TPR | PU and other materials. It includes:

① Bottom: the part of the front part of the bottom in contact with the ground and the part of the waist; ② heel: the part of the bottom surface in contact with the ground; ③ skin: attached to the heel to enhance wear resistance; ④ along the strip: attached between the upper and the sole, used for waterproofing, strengthening adhesion and aesthetics.

2. Midsole:

The invisible part of the sole part is located between the insole and the outsole and is made of special materials. The waist is pasted with a steel bar with the same curvature as the human foot, which is called hook heart or "waist iron". The role of the midsole is to make the sole firm and not easy to deform.

3. Foot pad:

The part of the sole part that directly contacts the foot, and the side facing the midsole is pasted with soft EVA (a synthetic material similar to foam material). The role of the foot pad is to make the foot comfortable and breathable when wearing.
