What are the characteristics of running shoes? Do running shoes have anti-slip effect?

Nowadays, more and more people are paying attention to sports and fitness, so there are more and more sports products on the market. Therefore, when purchasing some sports products, you need to pay attention to some issues. So what are the characteristics of running shoes? Do running shoes have an anti-slip effect?

According to the needs of biomechanics, running shoes can be divided into three categories: those that provide shock absorption, those that provide stability, and those that provide motion control. Running shoes that provide shock absorption usually have a softer sandwich sole to assist the foot in evenly bearing force during exercise and help the foot absorb shock. The shoe body is usually lighter and relatively less stable. Running shoes that provide stability usually have a column with even force on the sole or a sandwich structure on the inside. These special designs can prevent injuries caused by excessive eversion of the foot and provide good support and durability for the inner edge of the foot. Running shoes that provide motion control are usually harder, which can reduce or control excessive inversion of the foot and prevent ankle injuries. The weight of this type of running shoe is usually heavier than other running shoes. The structure is generally that the inner layer is a column with even force to control the inward rotation of the foot, and the sandwich sole provides durability; the outer layer of rubber is more wear-resistant.

Yes. First of all, we need to look at the material of the sole. Among the sports shoes currently sold on the market, many shoes have rubber soles. Although this type of sole is wear-resistant, it is easy to become brittle and break when it is cold, resulting in a decrease in the anti-skid coefficient. The soles of sports shoes with better anti-skid performance on the market are mostly made of TPR material, which is more wear-resistant and lighter. Secondly, when buying sports shoes, we need to look at the hardness of the sole. Although a too soft sole can increase the comfort of the shoes, it is easy to affect the center of gravity of the body when walking. Shoes with too hard soles are easy to affect the judgment of the feet on the ground when walking, and are not conducive to anti-skid. Best, when buying sports shoes, we need to look at the grooves on the soles. Sports shoes with deep and many grooves on the soles are not easy to retain broken ice and snow, and have better anti-skid performance, while sports shoes with shallow grooves are easy to slip when worn. The amount of friction generated by the contact between the sole and the ground is determined by weight and the coefficient of friction. The coefficient of friction is a numerical value of the friction between different materials. The higher the value, the greater the friction generated and the more anti-slip it is.

It is better not to wear air cushion shoes when running. Air cushion shoes are not good for the arch of the foot and are not very helpful for the knee joint. Cushioning relies on the arch of the foot and the meniscus. It is best to make the arch of the foot more adaptable. The main difference between cushion shoes and ordinary sports shoes is the use of air cushions. There is an air storage cavity that can form an air cushion between the upper and lower parts of the sole. The role of the air cushion is shock absorption and protects your knees during exercise. It is generally believed that the air cushion shock absorption protects the feet, which is a misunderstanding. In fact, it is the ankle design of the sneakers that protects the ankles. In addition, the air cushion will not play any role in bouncing.

If you want to buy the right running shoes, you should choose them according to your foot shape. You can judge your foot shape by the "wet foot test". The so-called "wet foot test" is to wet the sole of the foot and step on the dry ground, and then classify the foot into the following three types according to the shape of the footprint. Of course, many people's foot shapes may be between the two types, so it depends on which feature is more obvious. 1. Control action type: suitable for moderate to severe inversion feet and people with higher weight. It can improve the runner's control of the heel and running action, and can support the arch of the foot. Its external characteristics are thickened arch area and medium to heavy weight of the shoe. For example, NB 850 and Asics Foundation 8 are such running shoes. 2. Cushioning and shock absorption type: suitable for runners with good running skills, landing on the forefoot or middle of the foot, and supporting with the sole and the outside of the foot. The weight of the shoe is medium to heavy and the sole is thicker. Many well-known brands of running shoes have cushioning functions, such as Nike's AIR MAX and ZOOM series, New Balance's MR1080 high-end cushioning running shoes, adidas's representative cushioning running shoes are boost, Li Ning's "Double Crossing" is also a cushioning and shock-absorbing running shoe, and Asics' top cushioning flagship shoes include GEL Nimbus and Cumulus. 3. Stable type: suitable for runners with mild to moderate inversion of the foot, who use the middle and outer sides of the foot for support, and the weight of the shoe is medium. For example, Mizuno's Wave Nirvana series is the top series of stable running shoes, Li Ning's representative stable running shoe is "Lijun", and Asics GT-KAYANO is also a stable running shoe.
