1, the normal wear and tear of the sole of the heel more normal people walking, the heel will have more or less wear and tear, and wear position more concentrated in the heel outside, which is to maintain better balance, most people walk with a slight outward eight shape of the foot, resulting in the heel outside as a point of force, bringing passive wear. Normal people of this outward eight walking posture, the angle is generally between 10-20 degrees, more than 30 degrees need to raise alarm. Usually, if the newly purchased shoes, six months to wear off 20% or less, generally regarded as normal. Such as three months to reach twenty percent, indicating that your body may have certain health problems, should promptly go to the hospital testing, treatment. 2, the inner sole of the shoe wear larger tips X-shaped legs This situation may be due to the knee joints of both legs leaning inward, resulting in the outward bending of the calf. This way of walking can easily lead to joint sprains and injuries, and long-term uneven force can also lead to wear and tear on the cartilage outside the knee, leading to arthritis. In this case, the serious situation is called X-shaped legs, which is commonly known as “outward eight”. In the outer eight, there are also some people who suffer from hip contracture syndrome because they were always shot in the buttocks when they were young, and these people have serious shoe wear. You can simply do a test yourself, and knee squat, if you can’t squat, you should pay high attention to it. 3, the outer soles of the shoes wear larger tips O-shaped leg These people are mostly the two legs of the knee joint outward separation, resulting in the lower leg tibia turned inward at a certain angle. If serious, it is the so-called O-shaped leg or “inside the eight”. When you walk with an “inward” leg for a long time, the angle of your toes will also become larger, causing your knees to move outward and your legs to become deformed. As you age, the knee joint will become more painful and the joint will slowly age, leading to discomfort in the lumbar spine and other situations. 4, the sole wear asymmetrical tips legs of different lengths This situation is mostly due to the uneven force situation of both knees, the most typical symptom is that the legs are of different lengths. The cause of the short and long legs, in addition to congenital, may also be pelvic tilt, or even hip subluxation. In addition, the length of the legs are different, walking movements are different, the degree of wear on the soles of the left and right feet is usually different, the long leg that foot sole wear is small, the short leg that foot sole wear is large. 5, the overall wear and tear of the sole tips flat feet If you find that the wear and tear of their shoes are almost the same, then it is estimated that you are flat feet. For example, when the draft medical examination, conscripts will be asked to take off their shoes and step on water to stand out an imprint on the ground. If you have flat feet, it is a complete footprint. Because flat feet are congenital deformities, the elasticity of the foot is small, plus the center of the foot is in direct contact with the ground, compressing the nerves, and walking for a long time will hurt, so it will be eliminated. In contrast, a normal foot has an arch and the inside of the footprint is empty, with only the forefoot, heel and outside of the foot. And a flat foot is a light board, the forefoot, the heart of the foot, the outside and the heel can be shown. 6, the soles of shoes wear too fast hint hip or spine disease In fact, most people’s soles will wear, but not that these people have skeletal muscle problems, but a pair of shoes within 3 months wear 20%-30% can basically determine the body out of the problem. These people should go to the sports medicine department or rehabilitation medicine department for diagnosis as soon as possible. Common causes, there are hip joint diseases, like congenital hip subluxation, hip dysplasia, scoliosis, etc. Some scholars believe that there is some bias in such a statement. Everyone has different habits, different amount of exercise and exercise habits, and the rate of wear and tear will be different. So, it also depends on the symmetry. As long as the left and right wear is symmetrical and the wear is not particularly exaggerated, you don’t have to be too concerned. If the symmetry is not good, then you really need to pay attention. How to walk without costly shoes? In order to make your walk standard and graceful, but not costly shoes, walking posture is important. The correct walking posture should be head up, slightly tucked in, toes should be forward when stepping with both feet, minimize inward or outward bias, and the forefoot should land first when landing on the ground. For walking rhythm should also be well adjusted, especially women should not have small steps, dragging the heel of the walk, which will not only make the heel wear, but also affect the growth and development of bones, resulting in an unattractive gait.
