With the improvement of the quality of life, people’s awareness of foot care and health care continues to increase. “Insole”, a small object that was easy to be ignored before, is gradually coming into people’s field of vision. Traditional cotton insoles can no longer meet people’s needs due to their poor perspiration ability and easy sliding in the shoes. Sweat-absorbing, breathable, durable, and comfortable foot-shaped insoles will make those who suffer from flat pads all day long. Yiliang, once it benefits from use, it will become a loyal audience group; coupled with a large number of sports shoes, travel shoes, and casual shoes that are on the market every year, the need for normal loss of inner pads, the market capacity of high-quality and comfortable insoles will be huge. . In developed countries in Europe and America, more than 50% of people have used modern technology to prepare comfortable insoles. In the foot care industry in the United States, insoles account for half of the market share. In China, it is worrying. Most of the current insoles are simple in design, rough-in craftsmanship, single-purpose, and poor in materials. There are few foot care products in large-scale shopping malls and supermarkets. People buy insoles only for the simplest satisfaction. The original demand.</p>

<em><strong>The role of insoles></em></p>
<!– /wp:paragraph –>

1. Prevent the feet from sliding in the shoes. The footbed in the shoe is flat, but the sole of the human foot is not. Therefore, the sole will slide in the shoe when walking. Each step requires a little more effort during walking. Long-distance walking is more likely to increase various traumas. The three-dimensional insole can fill the space between the sole and the footbed, and reduce the sliding of the sole in the shoe.<br>2. Improve support and improve the stability of the pace. The foot-shaped insole on the heel can reduce the swing when the heel touches the ground during walking, thereby reducing fatigue and reducing the chance of trauma.<br>3. Shock absorption. There are two kinds of shock-absorbing insoles. One is to use hard cup-shaped heel support or add shock-absorbing paste. Because the hypertrophy of the human heel is a natural shock-absorbing function, as long as it is matched with hard rubber support or shock-absorbing paste with a suitable curvature, it can be used. Can play a good shock absorption function. The other is to use soft materials, such as Gel, air cushion, etc. to absorb the impact of heels on the ground, suitable for running, basketball, and other high running and jumping actions.<br>4. Correct walking and standing postures. This is the function that orthopedic insoles can perform. Many people are born and other factors. When standing, the spine and leg bones are not 100% perpendicular, or when walking, they sway left and right. This kind of bone and joint trauma can be corrected with the help of orthopedic insoles to correct the posture when walking and standing, thereby reducing the trauma.</p>

<!– /wp:paragraph –>

<!– wp:paragraph –>

According to the materials of the insoles currently on the market, it can be roughly divided into cotton insoles, insoles made of pure natural materials such as hemp, rattan, grass, paper, etc., leather insoles, GEL insoles, EVA insoles, high polymer breathable cotton insoles, and PU insoles. Large variety.<br>1. Traditional cotton insoles. It is made of pure new cotton material and belongs to the category of environmentally friendly insoles. Advantages: good air permeability, can absorb some peculiar smells, and has no toxic side effects on the skin.<br>Disadvantages: poor plasticity, no sweat, and ease to deform. In the process of walking, it often slides or rushes out of the shoes, which increases the troubles of wearing. Due to poor sweat absorption, the entire shoe is like heavy rain on a pile of loess, muddy, painful Unbearable for people with sweaty feet. At the same time, it does not have the function of deodorization.<br>In addition, most of these insoles are processed by hand-crafted workshops or simple small factories. Most raw materials come from recycled waste clothes, contaminated and worn-out bed sheets and quilts from hospitals, hotels, hotels, industrial scraps, and black cotton processing. Felt blankets and so on. Such insole materials are generally made of a new layer of fabric without any disinfection or sterilization. The bacterial content of this type of insole is seriously exceeding the standard, and it is an important source of transmission of athlete’s foot infection. The relevant departments call it garbage insole.<br>2. Pure natural environmental protection material insoles, insoles made of hemp, rattan, grass, paper, etc. Advantages: The material is natural and environmentally friendly, and has some antibacterial effects, and has good air permeability. Disadvantages: The workmanship is difficult to be refined, which affects comfort and aesthetics, and there is also the defect of easy-sliding in the shoe.<br>3. Leather insoles (imitation leather insoles). Advantages: comfortable and elegant, suitable for people with less sweat on their feet. Disadvantages: The leather of the leather insole will become stiff after aging, and the leather insole will only absorb odor, not deodorize, and has poor moisture absorption. Therefore, it is not suitable for those who sweat a lot and have bad feet.<br>In addition: this type of insole leather is generally processed by tanning and coloring, and most of them are pig lining and cow two layers, and cow three layers. The imitation leather insoles are mostly crushed and pressed by crushed leather ballast. Imitation leather insoles have poor air permeability, change color when inhaling foot sweat, and contaminate socks or upper lining.<br>4. GEL elastomer insoles (silicone insoles). Advantages GEL’s elastic body has super shock absorption, excellent cushioning, and long-lasting comfort, avoiding foot and joint pain and fatigue during walking and sports, reducing the concussion of the spine and back of the brain, suitable for people who often walk and exercise use. Disadvantages: poor air permeability.<br>5. EVA insole. Vinyl acetate copolymer, polymer material. Advantages: lightweight, good elasticity, good flexibility, not easy to wrinkle, suitable for various climates. Disadvantages: poor air permeability and poor resilience for a long time, but high-elastic EVA can solve such problems.<br>6. Environmentally friendly high-polymer breathable cotton insoles, represented by “Haiboli”, English high-poly, also known as “Poly you” poly you, the main ingredient is polyurethane, which has good air permeability and super strong Water absorption, excellent deformation resistance, good deodorization, and also have shock absorption and rebound functions, which are in line with the stress changes of the feet during the landing time, especially for long-term and high-intensity sports. It is a variety of brand sports, Ideal insole material for casual shoes.<br>7. PU insole. High-molecular polyurethane synthetic material. Advantages: high density, high hardness, toughness, wear resistance, good elasticity, not easy to wrinkle, mostly used for outsoles of shoes. Disadvantages: easy to yellow, poor elongation, poor air permeability.</p>

<em><strong>the cause of foot odor></em></p>
<!– /wp:paragraph –>

<!– wp:paragraph –>

The cause of foot odor is caused by the following factors.<br>1. Humid environment: the surface temperature of the human foot skin will rise from the normal temperature of 37 degrees Celsius to 41 degrees Celsius after putting on the shoes. In addition, the feet will expand with the increase in temperature, which makes the feet just full The entire space of the shoe, coupled with the friction of the sole when walking, will also generate heat. The sultry heat produces sweat. Every day, the feet emit a lot of sweat. There are more than 600 sweat glands per square centimeter on the soles of the feet. There are about 250,000 sweat glands in total, which is 2 to 4 times more than other parts of the body. About 60% of the sweat is discharged from the edge of the shoe, 30% is discharged from the base of the inner pad, and the rest will stay in the shoe, which will produce a damp feeling. In addition to moisture and salt, sweat also contains lactic acid and urea. When the moisture content is high, it is very conducive to the proliferation of bacteria and molds.<br>2. Sultry and confined space: When the shoes are tightly worn and the ventilation is not good, in addition to the increase of moisture, the ph value of the skin surface will change, from the original ph4.4 to about ph7, And will emit carbon dioxide gas, this environment is most suitable for the growth of certain bacteria on the soles of the feet.<br>3. The reproduction of bacteria: due to the additive effect of one and two factors, the growth of foot skin bacteria is caused. These bacteria can decompose the keratin of the skin, and the area and lactic acid components in the foot sweat. A variety of metabolites, such as methyl mercaptan, short-chain fatty acids, and ammonia, these flavors are mixed and tightly stuffed in airtight socks, will form an unpleasant foot odor.<br>4. The reproduction of mold: The hot and humid environment will cause mold to grow and form tinea pedis, commonly known as Hong Kong foot. The typical symptom is foot odor. 5. Too thick old keratin: Too thick old keratin, under the infiltration of sweat, will become a source of nutrients needed by bacteria and molds, promote the proliferation and reproduction of bacteria and molds, and worsen the formation of foot odor.</p>
