Shoes have always lived in the "bottom" of people's bodies. They carry the load of the body together with the feet, and they contribute silently and become the safety guarantee for people to move forward. With the development of the times, the functionality and aesthetics of shoes also conflict. Some consumers ignore the protective effect of shoes on feet in order to pursue beauty. In fact, from the perspective of physical health, when buying shoes, decoration and aesthetics are secondary.

There are 206 bones in the human body, 52 feet, 66 joints, more than 40 muscles and more than 200 ligaments. It protects the spine and brain and is known as a "natural shock absorber". Therefore, good shoes must first play a role in supporting, cushioning and protecting the foot, which is the basic principle of choosing shoes.

If you wear shoes that are too soft, shake relatively large, flat and thin soles and have no support, it will cause gravity to be transmitted to the knees, lumbar vertebrae and even cervical vertebrae when walking, thus causing damage to the spine and joints.

The second is to choose the standard shoes with the correct arch design. It will have strong shock absorption and decompression effects, so that the whole body weight borne by your foot will be evenly distributed on the soles of your feet when walking, and will not oppress your toes due to improper distribution, causing inflammation and relaxation of foot ligaments.

In general, buy shoes to look for the right size, buy the right size shoes. Shoe size includes two information: shoe size and shoe type. The shoe size is in millimeters, which represents the inner length of the shoe and should be selected according to the length of the foot. Shoe types range from one to five, representing the transverse circumference of the shoe. The larger the type, the greater the fatness of the shoe. The choice should be made according to the width and weight of the foot. It is suggested that the distance from the toe to the front of the shoe should be reserved for 10mm for adults and about 15mm for children in the growth and development period. The width of the shoe type needs to be determined according to the individual's foot type. For example, after the flat foot or the arch of the elderly collapses, the foot will grow and become wider, and wide shoes need to be selected.

When buying footwear products, be sure to shop around and buy products from regular manufacturers in large shopping malls, specialty stores, brand flagship stores and other channels as much as possible to avoid buying "three no products". When buying, you can choose brand shoes with certain quality assurance capabilities. In the process of purchasing, pay attention to check the production date, product name, product standard, three guarantees, product material and other identification contents indicated on the shoe box or tag, and purchase with caution if the identification information is incomplete.

Before buying, carefully check the appearance of shoes and initially perceive comfort. Usually the soles of the feet sweat more, so when buying shoes, first check whether the upper surface, lining and inner pad materials are soft, breathable, sweat-absorbing and comfortable. Secondly, check whether the sole material is too hard or too soft, too hard or too soft is not conducive to human activities. Thirdly, check whether the bonding part of the bottom is firm, whether the bonding part is open or peeled, and whether the main heel and Baotou are round and flat, the stitches are neat, and there is no needle skipping, disconnection, etc.

How to check the left and right balance of shoes? You can place your shoes on the floor and observe whether the heel is perpendicular to the ground and whether it is in full contact with the ground. In addition, the shoes should be observed from the front and back sides of the shoes left and right balance. If the left and right balance of the shoes is not good, the force on the feet is easy to be unbalanced, which can easily lead to changes in the negative gravity line of the human body, and even lead to knee arthritis, pelvic tilt and other diseases.

The sole has a great influence on the quality of shoes. Consumers should learn to check the folding and hardness of shoes. For optional shoes, the sole should be bendable and folding resistant, preferably about 60 degrees in half, and the bending point should be at the first 1/3 (about the axis of phalangeal joint). Bend the toe downward and press it. If the entire sole can be bent or twisted at will, it means that the shoe is too soft and the big toe will be sore and uncomfortable when walking.

The sole should not be too thin and too soft. Because the back 2/3 of the sole is the plantar fascia, the sole is too thin and too soft to provide sufficient support. The sole is too soft or too thin, and the relative shock absorption effect is also poor, which is easy to make the soles of the feet uncomfortable under the impact of each walk. At present, only children's shoes and special purpose shoes have requirements for sole hardness.

Try to buy shoes with shock-absorbing structure at the sole, elastic heel and anti-skid function at the forefoot. When people walk, 0.7 to 1.5 times the weight of the weight falls on the soles of the feet, and the reaction force will return to the ankle joints and knee joints. In severe cases, it may cause knee joint recession, waist or shoulder and neck pain. In order to reduce the impact, the sole or insole in the heel must have elastic cushion, in order to shock.

The heel of the shoe should be supported and wrapped well. The bottom area is too small or the heel is too thin, too narrow are easy to cause walking force line instability, easy to sprain the ankle.

When buying shoes, you need to try them on in person. When trying them on, you should pay attention to the fact that your feet will be bigger in the afternoon and evening than in the morning, so it is recommended to buy shoes in the afternoon or evening. The stretching state of your feet is different when standing and sitting. When trying on shoes, you should feel both standing and walking.

At present, with the increasing penetration of e-commerce platforms, many people will choose to buy online, which requires careful checking whether the product information is consistent with the merchant's web page statement. After receiving the product to verify the product information, and the actual product tag does not show the quality information advertised on the network. At the same time, it depends on whether the product instructions are accurate and comprehensive. Check whether the tag and logo of the product have the name, address, product standards implemented, and whether the basic information such as material, color and shoe number are accurately marked. For products lacking these basic information, the quality cannot be guaranteed and it is not recommended to buy.
