"Mom, let me see what happened to the shoes. What happened to Xiaolong's body? These shoes have only been worn for a few days, and it is impossible to grind them into this appearance so easily. " Daughter-in-law took the shoes in Li Nainai's hand, and the front of the shoes was severely deformed. "Go to the hospital tomorrow to see what's going on."
I didn't know until I went to the hospital that Xiaolong wore his shoes quickly, not because he was naughty, but because he was in the growing period, his bones grew too fast, and his shoes were bought too small, which led to toe wear. In the long run, it will easily lead to long nails or claw toes, and the soles of the feet will slowly deform.
"In the future, if you buy shoes for your children, you must buy a wide band. Children's feet grow fast, and shoes should be replaced in time according to the size of their feet. " After listening to the doctor's words, Xiaolong's mother and grandmother nodded yes.
In fact, as an important part of the human body, feet can reflect the health status of the human body. Through the wear and tear of the shoes that must be worn every day, you can easily judge what is wrong with your body, and you can also seek medical advice in time. Then how to judge what is normal shoes and what is abnormal shoes?
Wear of shoes is a normal phenomenon. After wearing shoes for a period of time, shoes will show signs of wear. Under the premise of balancing the force of the two feet, the sole and heel wear of the two soles will be more uniform. It's normal for a pair of newly bought shoes to wear less than 20% in 6 months. If the wear of shoes reaches 20%-30% within 3 months, you can consider whether there is something wrong with your body.
The wear of different parts of shoes represents the problems of different parts of the body. Next, I'll introduce you to five kinds of common shoe sole wear.
There are five kinds of common shoe sole wear, namely side heel wear, middle heel wear, toe wear, side toe wear and toe wear.
There are many reasons for the serious wear of the lateral heel. Common situations are varus foot, high arch foot and walking "inner eight" Hallux valgus is a common developmental deformity, which mostly occurs in newborns and male groups. Clinically, unilateral or bilateral feet have different degrees of deformity, and the ankle joint of the foot is subluxated, which makes the foot in the posture of varus and supination. After a long time, the lateral heel is prone to serious wear.
High arch feet can also cause lateral heel wear. High arch feet will make overweight tend to the outside of the foot, resulting in excessive stress on the outside of the heel. Therefore, the degree of wear on the outside of the heel far exceeds other parts of the sole. At the same time, this way of walking is very easy to cause joint sprain, and long-term uneven stress will cause cartilage wear outside the knee, which will lead to arthritis.
Walking in the inner figure of eight refers to the situation that when walking, the feet show the "inner figure of eight" and the calves will bend outward. Walking for eight hours for a long time will increase the possibility of joint injury; It is also easy to cause the wear of the lateral cartilage of the knee joint and cause osteoarthritis prematurely. Because walking for eight minutes will bend the calf outward, walking for eight minutes will also increase the pressure on the hip bone, which will cause bone pain when sitting. If it is not corrected in time, it is easy to form an "X-leg".
If there are obvious wear marks on the inside of the heel, it may be caused by eversion or flat feet. Hallux valgus is generally caused by congenital tendon dysplasia of the foot, which is common in children. In addition to congenital factors, acquired factors, such as impaired function of supporting ligament of foot joint, abnormal function of supporting arch muscle and excessive activity of subtalar joint, will lead to valgus in adults.
Flat feet are characterized by a flat arch. Patients with flat feet will tilt inward when the middle part of the sole touches the ground during walking. This will lead to wear of the inner heel. Compared with normal soles, the foot elasticity of flat feet is seriously insufficient. Will make the calf muscles overworked, resulting in tight calf muscles, which in turn leads to frequent cramps in the calf or swelling of the medial ankle joint. In addition, flat feet may also lead to pelvic forward tilt and low back pain.
If there are obvious toes protruding from the soles of the feet, it is generally not because there is something wrong with the feet, but because the feet are wide or the shoes are too small. But there is a high probability that it will bring foot disease. If the shoes are too small, the soles of the feet will be squeezed, which will cause uneven stress on the soles. In the long run, the toe joints will become unstable, which will deform the feet.
In addition, it may also lead to ingrown toenails or claw toes. This situation often happens to children with rapid physical development, such as the little dragon mentioned at the beginning of the article, which belongs to this category.
Hallux valgus is the main cause of lateral thumb wear. The clinical basis for judging hallux valgus is that the joint inclination at the joint between the big toe and the foot exceeds 15. Hallux valgus is a very common forefoot deformity, which will seriously affect the walking ability of patients.
The incidence of hallux valgus is mainly adults. The causes of diseases can be divided into internal and external causes. Internal factors are generally influenced by genetic factors. Studies show that 90% of hallux valgus patients have a family genetic history, and genetic factors are related to gender. When the mother is sick, the chances of her daughter getting sick will increase. Excessive foot pronation, muscle diseases and changes in estrogen levels will also increase the probability of hallux valgus.
The external cause of hallux valgus is largely influenced by shoes and socks. Many studies have found that wearing high heels and pointed shoes often increases the probability of hallux valgus. High heels can change the load on your feet and squeeze your toes. Long-term extrusion will change the shape of the forefoot, especially the big toe, and induce hallux valgus.
The phenomenon of shoe wear is mainly caused by oversized shoes. In order to adapt to the oversized shoes, the ankles will frequently rub the shoe mouth when walking, causing the inner side of the shoe mouth to wear.
Oversize shoes can also lead to overuse of the forefoot. When walking, the forefoot will unconsciously exert too much force, which will easily lead to acute pain in the tibia and calf. Repeated friction between feet and shoes may lead to heel blistering and plantar fasciitis.
After understanding the above five common ways of wearing shoes and their harm to health, how to avoid abnormal wearing shoes and how to treat these foot diseases are also on the agenda. Next, I will introduce them to you.
There are many foot diseases that can be solved by correction, such as "inner eight", hallux valgus, acquired hallux valgus and so on.
For the correction of "inner eight" and "outer eight", we should first pay attention to the way of walking and not stoop. When walking, hold your chest out, keep your back relaxed, try to force your front foot, control your heel to land smoothly, and keep your toes straight ahead, instead of taking the step of "eight inside and eight outside". When choosing shoes at ordinary times, you can slightly raise the places that are easy to wear and slowly change the center of gravity, and you can correct your walking posture over time. If the correction effect is not good, you should go to the hospital for orthopedic consultation in time.
For eversion, we must first change bad habits. Reduce the frequency of crossing your legs and try not to wear high heels or pointed shoes. Secondly, choose the right shoes. Under the guidance of a doctor, you can choose corrective shoes or valgus insoles for auxiliary treatment.
For the foot deformity that cannot be improved by correction, you can go to the orthopedic department of the hospital to treat it in various ways.
In addition to treating foot deformity by medical means, choosing suitable shoes can also assist in the treatment.
Choosing the right shoes is also an important measure to protect your feet.
For normal feet, you can choose wide-toed shoes. According to clinical observation, the toes of normal feet are thicker and shorter, and the feet are wider. Therefore, for people with normal feet, choosing wide-toed shoes will be more comfortable, and standing and walking for a long time will not be too tired.
For arch feet (including high arch feet and hallux valgus), their feet will arch when they land, and the impact force of their feet following the ground is relatively large. And because the arch is higher. When the sole of the foot touches the ground and needs to support the whole body weight, the lateral area of the sole touches the ground is smaller, the flexibility is lower than the normal foot shape, and the buffering energy is also poor. Therefore, for the arch, it is recommended to wear shoes with elasticity, air cushion or slightly soft and thick foundation.
When walking with flat feet, the soles of the feet will be excessively pronated, causing pain in the calves and ankles. Therefore, flat feet recommend shoes with slightly higher heels, or shoes with hard materials at the inner arch to support the soles of the feet.
For people who walk inside and outside, it is recommended to wear shoes with hard heels or arches, and it is not recommended to wear shoes with soft soles. Soft-soled shoes are difficult to correct and limit heel tilt, and may also aggravate foot deformation.
Finally, when choosing shoes, you should also choose shoes that suit your foot type, not too loose or too narrow. Especially teenagers and children with normal long bodies, at this stage, their feet are growing rapidly. When choosing shoes, parents should never buy wide shoes for their children, because their feet grow fast. If the shoes are small, put on new shoes in time.
