1500 What shoes do you need to wear for long-distance running?
1) structure of running shoes
To understand running shoes and choose running shoes, we must first understand their structure. Running shoes, or most sports shoes, are roughly divided into three parts.
1. The outsole (or outsole) is the bottom layer where the shoes touch the ground. Wear-resistant and anti-slip is its key point.
2. Midsole, between outsole and insole. Elasticity and foot protection are its key points. Midsole is also a high-tech part of running shoes.
3. Upper part, mainly above the insole, including the whole upper part of the shoe. Breathable, easy to put on and take off, beautiful is its key.
On the shoe wall of sporting goods store, pick up a running shoe and observe. From the perspective of the outsole, the outsole is generally covered with various special lines, and there may be many grooves in the middle. The color is mostly black and there are other colors, and the thickness is generally 3-5 mm. The main function of the outsole is to play a role of wear resistance and anti-slip in the process of direct contact with the ground, and the full lines and grooves play this role. The material of the outsole is generally carbon-containing rubber, which is more wear-resistant, with ideal anti-slip effect and weight.
Between the outsole and the brightly colored upper, there is often a white midsole. The thickness of the midsole is about 1-2cm, and its main function is to cushion the vibration from the ground. When running, the vibration transmitted from the ground to the body can reach about 8 times of the normal walking state. If there is no midsole, running will do great harm to the whole body. Therefore, various high technologies have been developed and applied to the midsole. For example, Nike's AIR PAD, Adidas' ADIPRENE, ASICS' GEL, Mizuno's WAVE, etc. The name is different, but the purpose is the same, that is, to find ways to reduce and transfer vibration and make you feel comfortable and safe during running. The material of the midsole, except the patented technology specially used by various brands, is mostly foamed rubber such as EVA or PU. It has good elasticity and light weight.
The midsole goes up, which is the upper part. This part is in direct contact with your feet (and of course through socks). It's like a protective sleeve, which protects your feet from wearing safely. Among them, the first is to touch the insole of your foot. If you look at shoes, you will find that there are many kinds of insoles. Indeed, this part is also permeated with high technology. For example, EVA is generally used as insole material, but the surface is treated, which increases the absorption and distribution function of foot sweat. There are also some insoles that can adjust the support to the arch of the foot to achieve the best fit between the foot and the shoe. The other part of the upper half is the upper.
This part is the most complicated and difficult part in shoe design. This mainly refers to how to balance the appearance, style and function of shoes. Big-name sports brands often launch many attractive new models every quarter, so that buyers can pay for bags. Functionally, this part mainly considers: breathability, comfort, personal protection of feet and ankles, firmness and convenience of shoelaces, etc.
Knowing the structure of running shoes, how to determine what kind of running shoes you need? Looking at sporting goods stores, each brand has several kinds of running shoes at the same time, even more than a dozen, and new buyers are inevitably dazzled. In fact, running shoes are generally divided into the following categories in terms of function and use:
(2) Classification of running shoes
First of all, the classification mentioned here is the general classification of running shoes by most running shoe manufacturers. If there are other classification methods, the starting point may be different. The classification here is mainly based on the user's requirements for the performance of running shoes and the purpose of wearing them. The differences mainly focus on the following points:
A. the ability to support the arch and heel of the user,
B. the ability to correct and protect the external splayed foot and the internal splayed foot,
C whether the sole is flat,
D. the weight and stability of shoes,
E. Road conditions at the running place
