1. What shoes are the shoe traces of the stream

The stream shoes are a kind of sports shoes. The shoe traces are often out of the water and water. This requires the drainability of the shoes to be good, and the sediment can also be discharged with the water to reduce the wear of the feet.

When you climb the waterfall through equipment and even bare hands, you are also required to have a certain climbing characteristics: in addition to the good friction effect, the pointed toe design of the pointed shoe -like shoe can be well designed.Find the support point, and the harder toe will also help protect the toes and play a sufficient protective role.

2. Detailed explanation of the characteristics of streaming shoes

Xiuxi shoes are necessary equipment for the stream.A pair of qualified stream shoes should include the following features:

1. Anti -slip

This is the main performance indicator of the stream shoes.There are often huge rocks in the Canyon stream, and there are also small stones and rigids.Some stones are raised on the water, while others are hidden underwater.The water flow is urgent, and the stone surface is Smooth and difficult to do; where the water flows are slow, it is covered with slippery moss.They have different shapes. If the soles are not slippery, you can think of how difficult it is to move forward.If the protection measures are not done well, it is possible to slip and be injured.

2. Drainage and sand exhaust nature

I often walk in the stream, how can there be no wet shoes.When the shoes enter the water, it will become sinking, and the gravel will wear the foot.Excellent streaming shoes have a full range of drainage and sand exhaust systems, and some can block the sediment into the shoe while excreted the water.Different stream -tracing shoes have different drainage methods. Generally, drainage is performed through the leakage outlet of the upper, insoles and soles.

3. Shock absorption

During the stream, you often jump between stones. The shock -absorbing shoes can absorb the impact of hard stone during the beating, and it will not feel so painful.The cushionability of the shoes is mainly achieved through the midsole.The riverbed is uneven and the depths are different. When walking on a relatively shallow riverbed, the good buffer performance can filter the feet brought by the stone bottom stone.

4. Stepicality

The Xiuxi movement is not only active in the water, but also travels on the land.Everyone has experience, and shoes are much more difficult than other clothes.The wet shoes will be greatly discounted, and the foot feels poor when walking, and it is easy to breed bacteria.When the weather turns cold, the feet wearing wet shoes are cold, and the whole body is also cold. People with poor constitution are prone to get sick, so the quick -drying performance of the stream shoes is also particularly important.

5. Solid toe

Presumably, you all have the experience of your toes on the bedside, but it feels quite sour.The feet are inevitably bumped during the stream, especially in areas where the water quality is turbid.It's okay to touch it. If you are serious, you have to enter the Hospital because stones are harder than imagined.The shoe of the stream should have a solid toe to protect our toes properly.

The difficulty in the stream of the river has higher requirements for shoes.When some routes meet the Shenzhen -Lake blocking roads, they may need to move forward from the roots of the rock walls on both sides; some routes need to crawl and climb the waterfall.In this case, some characteristics of rock Climbing shoes should also have some characteristics:

(1) The soles should not be too hard

The soft sole brings a good foot feeling, and it is easier to find the support point on the slippery rocks.

(2) The toe should not be too narrow

The narrow toe may get stuck in the rock wall cracks. The wider toe is not only comfortable to wear, but also increases the contact area with the rock surface and enhances friction.

Choosing a pair of good stream shoes is only one of the preparations for the streaming activities beforehand. Only by continuously strengthening physical fitness training and technical exercise of the stream, can you better enjoy the stimulus and happiness brought by the Xixi campaign.

1. What face shape is suitable for Toad mirror

Toad mirror, a type of Sunglasses, large lenses, light colors, windshields, Sun protection, sunscreen, and sunscreen. In the 1980s, they became popular in urban youths and became the special favorite of fashionable men and women.SoClam mirrorWhat face shape is suitable?

What kind of face person is suitable for people? Of course, people with no face shape are suitable for wearing toad mirrors.Retro -style toad mirrors are relatively wide, suitable for friends with high faces and corners, and higher nose bridges.If you are a friend with a Square or small face, your nose is not high enough, then try not to choose a retro -style Toad mirror.

2. How to choose Toad mirror in different faces

But if you really love toad mirrors, you can also reduce this discomfort by buying different types of toad mirrors:

1. Round face

Suitable for glasses with a slightly thicker frame, cold lens color, and darker colors, with the visual effect of "tightening" face.Too gorgeous yellow, red lens or frame lines with slender and soft Sunglasses will set off the face larger.

2. Small face shape

It is suitable for wearing fine frames or frameless glasses to choose elegant blue, purple, light brown and other lens colors, which will have unexpected effects.

3. Long face shape

You should choose a flat or curved mirror, a slightly thick mirror foot to weaken the slenderness of the long face.The slender face is generally skinny. Choosing a pink or wine -red lens with a more feminine flavor can increase the brightness of the face.

4, Square face

It is advisable to choose a Sunglasses with a narrow width and a Smooth four corners of the frame. Too large and too large mirror frames will only make the face look more Square. The color of the lens is better brown.

5, apricot face

Suitable for the lens to choose the lighter color, the fine metal frame or the frameless glasses, to weaken the weight above the face, so as not to make the upper face that was originally widened.

6, inverted triangle

Eastern glasses with thicker frames, darker colors, and slightly width of horizontal width should be used to adjust the proportion of up and down, which visually coordinated.

3. Recommendation of Toad mirror models of different faces

1. BL8118 and 8116, 8100:These styles are particularly suitable for Square faces, which can modify the face shape well.

2. BL8117:The design of the small box is suitable for most face shapes, and it also meets the aesthetics of most dads.

3. BL8115 and 8097, 7199:The polygon design, suitable for round or face width, can modify the face shape.

Except for 7199, the other styles are made of stainless steel, which is very elastic and lightweight and does not pinch the face.The lenses are high -definition nylon polarized mirrors, anti -glare, looking softer and clearer to see things.

1. winter sports shoes buy leather or mesh

In winter, if you choose a mesh on sports shoes, you will have a better breathability. Those who love sports, choose the mesh comfort, and it is easy to clean.If you choose a sports shoes with leather noodles, the warmth will be better, but the softness and comfort of the shoes may not be good.If the local winter is not particularly cold, you can choose the mesh.If the weather is cold, choose leather sneakers, so that the snowy days will also prevent the shoes from getting wet and not comfortable to soak their feet.

2. What are the differences between sneakers and leather surfaces

1. The difference in material

The upper of the mesh sneakers is mesh or PU mesh synthesis. The mesh sneakers are light in texture, the overall quality of sneakers is relatively light, and wearing is relatively light.The mesh sneakers are divided into two types according to the different number of mesh. One is that the surface of the upper is only the surface of the surface, and the single -net sneakers with fabrics inside; the other is the surface and inside of the upperDouble -net sports shoes.

The overall appearance of the upper of the leather sneakers is made of leather, which contains fabrics.Leather sneakers are mainly divided into three types of leather materials, which are PU -made sneakers, sports shoes made of ultra -fine fiber, and natural leather sports shoes.Among them, the price of PU materials is relatively cheap, the price of super fine fiber sneakers is relatively high, and the price of leather sneakers is higher. Now leather sneakers are mostly PU fabrics.

2. The difference between breathability

The material of the mesh sneakers is mesh and has a lot of breathable holes, so it has good breathability, especially suitable for being worn in spring and summer.Dry.

Everyone who passes through the leather sneakers knows that the breathability is relatively poor, especially when sweaty feet are hot in the weather, wearing leather sneakers will be very smelly.However, leather sneakers have a good anti -wind and warm effect, and can be worn in cold days.

3. Differential wear resistance

Compared with mesh sneakers, leather sneakers are more strong and wear -resistant.However, the leather sneakers are more likely to have creases, and the creases of sneakers on the mesh surface are not obvious.

4. The difference between cleaning convenience

Compared with the mesh sneakers and leather sneakers, it is more troublesome to clean, and the mesh is relatively dirty. It takes some time when cleaning.The leather sneakers are more convenient to clean. After the upper is dirty, you only need to use a humid towel to wipe it clean. It is very convenient.

5. The difference between comfort

The mesh sneakers are soft and light, and can be bent at will. It is still very comfortable to wear. The mesh sports shoes are mostly used for running shoes.The longer the leather sneakers wear, the more fit with the feet, and more heel the feet when you do exercise.

6. The difference in appearance

The color of the mesh sneakers is relatively soft and there are diverse styles; leather sneakers are more bright and gorgeous than mesh sneakers, and they are diverse in style.Both shoes can meet the needs of different people, and they are very fashionable.

[UV -proof glasses] How to identify the UV -proof function of Sunglasses, what is the coating

What is UV -proof glasses?

The light emitted in the sun is: visual light, infrared, ultraviolet rays, etc.The ultraviolet rays are seriously harmful to the Skin, eyes, etc. of the human body; the ultraviolet rays in the light released by the sunlight are divided into UVA, UVB, and UVC.It is the light of burning black Skin. Most corners of the eyes will absorb this UVB light, so it is necessary to block this light source.

Because UV glasses have the function of polarizing light, they can block all harmful light without affecting the visual light through, which can truly achieve the function of protecting the eyes.

How to identify the ultraviolet function of Sunglasses

Selecting Sunglasses depends on its lens quality, and pay special attention to the function of Sunglasses.So, how to identify whether Sunglasses have the function of anti -ultraviolet rays?In fact, it is not difficult. Put the Sunglasses on a 100 yuan RMB and use a purple light to identify it.

Experts said that the main role of Sunglasses is to prevent strong light and string light, especially ultraviolet irradiation, which protects eye health in summer and is not damaged.

Therefore, when purchasing, you must pay attention to whether there are "UV400" and "UV" logos on the lens and packaging. At the same time, the UV -proof test is also required.

Method 1. Look at the label of Sunglasses

There are Sunglasses with anti -ultraviolet function, generally there are several clear ways:

a) Mark the "UV400": This means that the lens's cut -off wavelength of ultraviolet is 400nm, that is, the maximum value of the maximum value of the spectrum transmission ratio of less than 400nm in the wavelength ()

b) Mark the "UV" and "UV prevention": This means that the lens's deadline for ultraviolet is 380nm, that is, the maximum value of the maximum value of the spectrum transmission ratio of less than 380nm below 380nm;

c) Mark "100%UV absorption": This means that the lens has 100%absorption function on ultraviolet rays, that is, its average transmission ratio in the ultraviolet interval is not more than 0.5%.

The Sunglasses that meet the above requirements are Sunglasses that truly have protection for ultraviolet rays.

Method 2. Use banknotes to verify

In the absence of instruments, ordinary people can also detect whether Sunglasses have the function of anti -ultraviolet rays.

Take a banknote, put the Sunglasses on the anti -counterfeit watermark, and use the banknote pen or the banknote inspection machine to take a look at the lens.If you can still see the watermark, it means that this pair of sun mirrors are not anti -ultraviolet. If you can't see it, it means that this pair of sun mirrors is anti -ultraviolet.

What is the coating of UV -proof glasses

The most effective and most commonly used method to avoid radiation light caused by damage to the eyes is to wear protective glasses.The so -called protective glasses are a filter that can change through light and spectrum.

This type of glasses is divided into two categories. One is absorption and one is a reflex. The former uses the most.

When the lens is manufactured, a part of the metal oxides are added to the general optical glass formula, such as iron, drilling, chromium, cricket, nickel, manganese, and some rare earth metal oxides such as harmony.

These metal oxides can make the glass selectively absorb the electromagnetic waves in a certain band of light, such as the oxide of the and iron can absorb ultraviolet rays in large quantities.Using this glass lens can reduce the amount of some wavelengths through the lens, reduce or prevent damage to the eye.

1. Absorption filter

Also known as Sunglasses.The transmission rate of visible light is about 20%, and the absorption of ultraviolet and infrared is better.There are many colors such as light green, light gray, and light tea, which are used to make sunshade and snow work protection glasses.

Among them, light gray lenses have minimized color recognition; light tea glasses make the blue sky look darker, which reduces the green light through it; the light green lens reduces red light through.

Second, reflective filter

The absorption filter is absorbed by the lens to some wavelength light to reduce the strong light in the eye, but because the lens absorbs certain light, it becomes heat and release, especially the infrared lines and other waves are longer.The light of light makes the eyes feel uncomfortable due to the accumulation of heat.

In actual work life, many situations are combined with absorption and reflective type, that is, a layer of high reflection membrane is placed on the color lens to make the filtering effect more, such as welding, chlorine -library welding, plasma cutting and other operators.You can use this method to solve it.

1. What are the design of training shoes

training shoes are a specially designed sports shoes for high -intensity sports training to achieve the purpose of improving physical fitness and sports performance.training shoes are different from ordinary casual shoes or sneakers. They are designed for athletes and crowds who are preparing to perform high -intensity exercise. They have more powerful support, abrasion resistance and stability, and more comfortable dressing experience.

The design use of the training shoes is mainly to provide sufficient support and protection in the sports training process to ensure that the strength of the body can be fully used and make the exercise effect more outstanding.training shoes has a variety of characteristics, such as technical expertise in strength, abrasion, stability and other aspects.These characteristics can give the best support in the foot during the training process, thereby reducing the pressure of the body and preventing possible damage in exercise.

2. design details of training shoes

The previous article has simply learned about the design of the training shoes, let's take a look at the design details of the training shoes!

Comprehensive training shoes focus on details, such as using breathable materials to improve comfort, use non -slip Shading to enhance grip, and special cushioning technology to reduce exercise impact.These designs are to ensure that wearers can get the best protection and comfortable experience in various environments.

Third, what characteristics should professional training shoes have

1. Shocking:Fingers that the soles of the shoe absorb the effect of impact shock when the feet are absorbed.For example, air cushions, PU, MD, EVA, etc. all have shock -proof functions, especially air cushions are generally valued by people.When human feet are on the ground, the impact of the ground on the human foot is usually 2-3 times that of the human body, especially when bouncing can be as high as 10 times, and good shock-proof devices can reduce this impact.Atmospheric gases, when the feet fall to the ground, it can disperse the impact through deformation to achieve the effect of shock absorption.Then avoid the damage caused by excessive vibration.

2. Wingtability:The athletes will twist in different parts of the feet in different directions when turning, back, and side -by -side feet, which is prone to sprains.Professional training shoes will install a device with high -density materials in the inner side of the feet and the feet bow to prevent the people's feet overdoing excessively during exercise to avoid sprains of exercise.

3. Return:The return of energy means that the soles of the shoe can store the energy generated by the ground. When the feet need to do the moment before the ground move, the sole will return the energy to the foot.Among them, the air cushion performed obviously. When the person's feet landed, the feet were given the air cushion energy, and the air cushion deformed after the air cushion was lift.At the same time, the air cushion helped his arms through the energy rebound, making the athlete Running faster and jumping higher.

4, footability:Finger shoe design, structural design (such as gangs, sutures, important efforts, structures, etc.) and the use of the superior telescopic characteristics of various new high -tech materials, making consumers feel wearing a fit.

5, bending:There are many factors that affect the effect of a pair of shoes. The design of the upper, the insoles, the midsole, and the outsole will all affect.The general requirements are that the bending parts must be consistent with the bending parts of the feet and meet the principles of sports physiology and motor mechanics.

6. Stop slipping:It refers to the outsole's stop slippery effect or grip. When the anti -slip effect is insufficient, it will not only cause the risk of slippery, cause exercise damage, but also affect the user's motion performance.The anti -slip effect is mainly reflected in the application of the bottom material and the design of the soles of the shoe. Depending on the motion method, the setting and design of the anti -slip effect will also be adjusted accordingly.Professional sports types often have good results in stopping.
