When designing the shoe last, it is necessary to consider the height of the heel. This has a lot to do with the wearing comfort of the shoe, and what is the relationship between the heel and the person's weight?
At rest, the person's center of gravity is between the body's cheekbones and the navel. As the position of the person's center of gravity is relatively high, the underside of the person's feet serves as a support surface and is relatively small. Inevitably, there are unstable factors in standing and exercising. There are: First, the contradiction between the center of gravity of the person and the supporting surface; the other is the relationship between the structure of the shoe and the center of gravity of the person.
When people put on shoes, the landing portion of the sole becomes the support surface for the person's weight. Because the shoe is not an integral part of the human body, but is the medium that the human foot contacts with the ground station, the structure of the shoe must have a certain influence on the center of gravity of the human body. People have this experience, in maintaining the normal balance of the human body, shallow shoes, no shoes with the main heel, hollow sandals, all-season sandals full of bad shoes compared to lace shoes, the former's wearing stability is worse than the latter . The main reason is that the former cannot be tightly wrapped and tied to the feet of a person, and cannot help people grasp the center of gravity in the movement; while the latter can closely wrap and tie in people's footsteps. There are associate professors in the movement. Grasping the focus.
In the process of walking, the force of the human body acting on the shoes is mainly borne by the heel and the forefoot. Therefore, the impact of leather shoes on the weight of people is great. One is the influence of the heel height on the person's center of gravity; the other is the influence of the area on the person's center of gravity; and the third is the influence of the heel as the body's support on the person's center of gravity.
People all have this experience, when put on with a large low-heeled shoes, compared with wearing high-heeled shoes with a small face, the feeling of maintaining a smooth body, the former is better. This is because the wearing of heels with large low-heeled shoes is not too high and the support surface is large when compared to when he is on the barefoot; when people wear heels with very small heels, the body's center of gravity is improved. More often than not, the area of ​​the support surface is greatly reduced.
When walking, no matter how high the heel, in the body does not talk sweetly, the center of gravity is constantly adjusted, the stress point of the bottom of the shoe must be a multi-point cyclic support. However, among these support points, the lower edge of the calcaneus is the main stress point of the person's center of gravity, because it is in the center of the heel at the bottom of the human foot, and according to the rule of the foot, the site is at 13% of the foot band. Therefore, in the specific design of the heel, no matter how high the height, how strange the modelling, first of all, but also must follow a design principle: with the seat surface, with the column and the heel must penetrate and diet live in the lower edge of the calcaneus Vertical line between the ground. · The old shoes at home are like this to transform big spikes · Old shoes don't stupidly throw away so that the shoes "open" Put a physical insurance on your shoes · How to clean the matte surface of the shoes? · Breathable, antibacterial, deodorizing socks with it to avoid off shoes ·Sports shoes's little tail actually has these 3 functions you certainly don't ·High-heeled shoes audio sound? 4 coups to ease you learn a few ·How to choose shoes during pregnancy?
