For patients with knee joints, the ideal warm -up activity method is: put the knee joints on the position of irreplaceable position, such as sitting position, knee flexion, irreversible.At this time, rotation and motion of the knee joints, decreased joint pressure, and the friction between the joint surfaces is greatly reduced, which is conducive to protecting the injured joint cartilage and half -moon plate.

1. What material is good for football shoes?

When buying football shoes, the material of football shoes is easier to ignore. In fact, the material of football shoes has a great impact on the performance of football shoes.There are many materials for football shoes, so what kind of material is good for football shoes?

1, Kangaroo Skin

This is the most iconic football floper. For a long time, kangaroos are the top identity symbols. So far, some players think that non -kangaro leather football shoes are not top -level, and they are not even real professional football shoes.The characteristics of kangaroo leather are soft, thin, tough, breathable, and waterproof performance. It is the best natural leather on the planet. It is used in football shoes with high confrontation, high tearing strength, better touch, waterproof, and breathable performance.It is the most suitable.However, because the kangaroo itself is not large and it is a good animal, there will be a lot of scars in the primary Skin. There are not many parts that can be used to make football shoes. In addition, only Australia exports kangaroos, so the production cost of kangaroos leather football shoes is compared to the production costs.High, the price is more expensive.The disadvantages of kangaroo Skin are also reflected in too soft and easy to collapse or excessive extension, that is, it is easy to deform or cross through after actual combat, and the sense of wrapping is greatly reduced; it is easy to open the gel.Too compatible; unsuitable for the rain, the natural leather will be peeled, loose, and aging.

2Cowhide

In the past, cowhide was generally used for non -top -level football shoes, mainly because the cowhide also had a soft touch and good breathability, and the cost of raw materials was low.In recent years, due to the rise in the cost of kangaroo Skin, many brands have replaced the kangaroo Skin with tanning cowhide or calf leather, and used on top -level football shoes.At present, the tanning technology of leather manufacturers can be said to be the pole, and the texture of tanning cowhide or calf leather has been infinitely close to kangaroo Skin.However, the toughness and waterproofness of the cowhide are not as good as the kangaroo Skin, which is more obvious after actual combat, which is relatively prone to deformation, peeling and loosening on the surface.

3, Artificial fiber

The application of artificial fibers on football shoes is to make up for the shortcomings of natural leather. For example, although natural leather is soft, it is poor; natural leather is easy to deform after actual combat; natural leather is not suitable for rain war; natural leather is easy to open glue, and it is easy to open glue.Poor durability; natural leather is not suitable for adding too many patterns, colors, coatings, or auxiliary designs on the surface because it is easy to peel off.After years of development, the artificial fibers of football shoes can not only make up for the many shortcomings of natural leather, but also basically simulate all the advantages of natural leather, and it is more durable and the cost of raw materials is lower.The gradual replacement of natural leather is the development trend of football shoes.Of course, artificial fiber fabrics are also divided into different Levels, corresponding to different Levels of football shoes.We are generally called good artificial fibers as ultra -fiber, and the difference isPUEssenceFinally, it is necessary to add, poor breathability is a prominent problem showing most artificial fibers.

4Fabric

In the past two years, fabric fabric football shoes have sprung up like rain. The purpose is to provide the most natural sense of barefoot. The most representative is Nike poison and ghost cards.It was once difficult for us to imagine how fabric fabrics were applied to football shoes, because they were worried that the fabric could afford such a high -intensity confrontation, but the era of change has arrived.The first is poisonousnikeskinThe fabric, through a special weaving method, shows the bumpy three -dimensional lines of the upper, and is fixed with a hot melt film; while the ghost card is used in breakthroughFlyknitThe yarn provides the degree of fit like socks. Of course, the surface layer still has to rely on the hot -melt film to increase the strength.The fabric fabric football shoes do bring us an unprecedented sense of barefoot experience, but the prominent problem is that the production cost is high, the price is high, the sense of power is average, and the durability is insufficient.There are also some entry -level football shoes that also use fabrics, but that kind of fabric is commonly known as "cloth", which is a tight -dense fiber cloth. The cost is low but wrapped, support, power, and durability.

5, Artificial leather

The strength of artificial leather leather football shoes is okay, but its cortex is very hard. It is very bad to kick the ball and the foot feels.Relatively speaking, it is more suitable for students, or those who play football on land or cement.

6ArtificialPU

ArtificialPUQuality football shoes are also very popular football shoes.There are many types and qualitys of it, which is very different, so the applicability and price of sneakers are also very different.PUQuality brand football shoes are also three or four hundred yuan in the market.

What is the material of football shoes soles?

In addition to the material of football shoes, the soles are also important. The soles of football shoes generally have the following materials:

1. TPU

The full name is thermoplastic polyurethane, which is widely used on the bottom of each level of football shoes. It has the characteristics of tough, wear -resistant, transparent, and low cost. It is very in line with the requirements of high -strength confrontation and pattern modification of football shoes.The disadvantage is relatively heavy.

2. nylon

The nylon outsole has only developed in recent years. As modern football is becoming more and more pursuing fast, football shoes must reduce weight, and the lighter and stronger nylon has become the best choice.But the disadvantage of nylon is insufficient toughness, non -transparent, and high cost. Generally, it is only applied to football shoes of the top or above.

3. carbon fiber

Its characteristics are light quality, high bombs, and unique high -end visual sense, but the disadvantage is that the cost is very high, and the requirements for the use of the site are also very high. Generally, it is applied to super -top football shoes.

4, rubber

Generally, the rubber outsole shoes are crushed nails and flat -bottomed football shoes. Because the venue is relatively hard, rubber has a certain cushioning performance, and the friction can also meet the needs of the grip.
