Heelys used and guided

[This site - shoes and life] I. How to choose style

At present, there are two types of domestic walking shoes: manual and automatic models.

1、Automatic Heelys

The automatic mechanical design of the Heelys has its own safety hazards. Generally, the automatic models have a long button behind the heel. The insider calls it the mouse tail. When the children are down the stairs or when they are in crowded people, they are careless. When an external cause hits the back button, the soles of the wheel will pop up instantly. Under unsuspecting circumstances, the child will often be unable to control the balance and cause a fall. If this happens on the stairs, the consequences would be disastrous. Fatal "is not an alarmist. This type of automatic walking shoes not only affects the health but also the relationship between life and safety, so it can never be bought or worn.

2, manual models of walking shoes

Manual models of Heelys wheels can be disassembled. When the child is playing, put the wheels on it. When not playing, remove the wheels and wear them as ordinary sports shoes. When a child concentrates on playing, he or she will choose a good venue and be mentally prepared. If he or she is not playing some difficult moves, he or she will generally not wrestle.

3, evaluation

So, is the manual version of the Heelys shoes to wear it? Although the manual models of Heelys shoes are not as dangerous as the automatic funds, but also affect the health must also meet the following two requirements: one, with the height must not exceed 3cm; The shockproof performance of the sole is better. It is understood that at present, only cyberspace walking shoes produced by the Brother Group can meet this requirement. So how can Cyberjumper meet this requirement? It depends mainly on Cyberjourne's selection of shoes according to international standards. The outsole must be made of rubber material, and the midsole must be pu material designed and produced. Heelys because of its functional problems, the sole is divided into a big sole and a midsole. The big sole and the common sole have to be in contact with the ground. Rubber is a wear-resistant, soft material. It is the sole sole material currently selected for international standards. The sole of Cyberjour's heel shoe is rubber with 40% rubber content, which is 10% higher than 30% of the international standards for shoes.

Second, how to see if the Heelys shoes are harmful

1, Heely heels should not be too high

The impact of walking shoes on children is mainly in the heel. The child is in a period of skeletal development can not wear high heels, so, Heelys shoes can not be too high is the key, the international standard with the height of not more than 3CM is qualified shoes. At present, the most popular manual models of Heelys shoes in the market have increased in height or height, and the heels generally exceed 5cm. This type of shoes has an impact on the health of children. At present, apart from the fact that China Cyberspace’s heeled heel height does not exceed 3cm, and it meets the international high requirements of children’s shoes, other Heelying shoes have failed to meet this requirement whether they are outside or inside. Therefore, it is a prerequisite that the heel can't be too high. For the sake of children's health, please do not buy high-heeled shoes when you buy explosive shoes.

2, heels shoes should not be too bad

(1) The composition of the heel shoe sole - Outsole

The outsole of outburst soles is usually made of rubber or TPR plastic. These two materials are very different in performance. Rubber soles are bent 180 degrees, 1000 times without cracks, TPR bending 180 degrees, 100 times will crack, In terms of wear resistance, there is also a difference between the world and TPR. The TPR bottom is continuously working on a professional abrasion tester for half an hour, and the sole pattern is completely flattened. Because Heelys is a sports product, in particular, the strength, toughness and wear resistance of the sole are very high. According to the international standard sole requirements, the contact area between the big bottom and the ground must be rubber and contain no less than 30% of glue. However, at present, most of China's Heelys used a TPR (a plastic name) sole as the sole, and this sole material is only allowed to be used on young children's shoes that are not able to walk at the age of 3 in accordance with international standards. The disadvantage of this material is that it is not resistant to wear and there is no softness beyond 2 mm. Heelys is a sports product that generates vibrations when gliding, because this material has a high hardness, and although the sole is very thick, the shock absorption effect is poor. Many children will feel heel pain soon after wearing this type of walking shoes. This is the reason. This kind of problem will affect the wearing comfort, and it will cause injuries to the foot muscles and foot meridians, which will seriously affect health.

(2) The composition of the heel shoe sole - midsole

The midsole of the Heelys is the key to quality. The role of the midsole is to change the hardness caused by the wheel frame on the sole, and to prevent the shock when sliding. Therefore, the material requirements for the midsole are very high. The international standard of the Heelys shoe requires a pu material in the midsole. The advantage of the pu material is that it is softer and more flexible than rubber, and it has a high density and is not easily deformed. This type of pu material is also a designated requirement of the shockproof pad for basketball shoes in an international standard. The PU material is 4 times higher than the PP density, the elastic modulus of the PU is 8 times higher than that of the PP, and the seismic value of the PU is 5 times that of the PP. At present, most of the walking shoe manufacturers do not produce according to international standards, and many even use TPR plastic outsole, this plastic is not wearable and easy to break even far less than the rubber performance; and the basic manufacturers of midsole use foam uv (is daily See the use of white foam board for electrical appliance packaging. This material is not tough, there is no flexibility, the density is very low, will not rebound after compression deformation, so it needs to be very thick to ease the heel pain caused by the shock. Here you should be clear why the radius of the Heelyskin's wheels is at most 1.9cm. That is to say, the highest point of the heel's sole is less than 2.0cm. Why is the sole made to be 5cm or even higher?

Third, how to determine whether the shoes are safe

This mainly depends on the style of shoes. At present, there are two types of domestic walking shoes, manual and automatic.

The automatic mechanical design of the Heelys has its own safety hazards. Generally, the automatic models have a long button behind the heel. The insider calls it the mouse tail. When the children are down the stairs or when they are in crowded people, they are careless. When an external cause hits the back button, the soles of the wheel will pop up instantly. Under unsuspecting circumstances, the child will often be unable to control the balance and cause a fall. If this happens on the stairs, the consequences would be disastrous. Fatal "is not an alarmist. This type of automatic walking shoes not only affects the health but also the relationship between life and safety, so it can never be bought or worn. Manual models of Heelys wheels can be disassembled. When the child is playing, put the wheels on it. When not playing, remove the wheels and wear them as ordinary sports shoes. When a child concentrates on playing, he or she will choose a good venue and be mentally prepared. If he or she is not playing some difficult moves, he or she will generally not wrestle.

Fourth, how to understand the comfort of the shoes

1, see if the size fits

2, see whether the shoes are comfortable, breathable
