1, which makes the skin of feet age too fast.
First of all, compared with ordinary slippers, flip-flops constantly beat the back of the sole, because flip-flops only have two straps in front of the shoes. According to the principle of physical fulcrum, when the heel is in contact with the heel, the force is great. In this way, the skin of the heel will become hard, because the foot will become dry when exposed to the air. If it becomes too dry, hard skin will crack. Whether it becomes hard or cracked, it will make the feet look very old, which is really an extremely indecent thing, especially for girls.
Secondly, because the design of flip-flops is too simple, most of the feet are exposed to the air. Of course, this is not the main thing. The most important thing is that in the season of wearing flip-flops, there is often strong sunshine and rich ultraviolet rays. In this way, not only the feet will be tanned in a short time, but also ultraviolet rays will affect the skin and induce skin cancer.
2. Foot tendon and bone injury.
The main principle of flip-flop walking is to lift the two straps in the middle of the shoe by the strength of the toes and drive the whole shoe forward. In order to hold the shoes firmly, the toes will unconsciously tighten for a long time, and they will curl up and grab the soles. This twisted state will last for a long time, leading to tendon strain under the toes and even nerve inflammation.
In addition, although people's foot bones are usually short and not easy to be injured, there is a row of slender phalanges in the first third of the sole of the foot, which is not so strong. Flip-flops greatly increase the pressure on the arch of the foot and its surrounding ligaments, which will not only cause inflammation, but also lead to stress fracture of the phalanx.
3. Causes waist discomfort, with eight characters inside.
It is said that when people wear flip-flops, they often unconsciously change their gait, the frequency becomes faster, the number of steps becomes smaller, and their ankles turn inward to hold their shoes. Moreover, when they lean forward, their knees will naturally bend, and the spine at the waist will also bend. After a long time, it will not only turn the pace into an internal picture, but also cause pain in the knees and spine, and even cause problems such as sciatica. Children's bones are not fully developed, so it is best not to wear them.
4. Feet are more likely to get hurt.
When people walk on gravel roads and muddy roads, flip-flops can't provide any protection. Think back, when you were wearing flip-flops, did you get many cuts, stab wounds and abrasions? Buckle sandals are a healthier choice. Not only do your toes not need to bend and tighten your shoes to prevent them from flying, but they can also provide better protection for your ankles and heels.
Even though the probability of sciatica is relatively small, there is no denying that you may be the lucky one.
In this case, flip-flops can't be worn often.
Of course, we are not saying that we must completely abandon flip-flops. They are very suitable for beaches and swimming pools, or for bathing in the gym. Don't forget to protect your feet if you have to wear flip-flops. Here are some ways to protect your feet.
Tips for foot protection:
First, flip-flops can wear 1 hour at the longest.
Tell everyone that flip-flops may be harmful to your feet, not that you should never wear flip-flops, but that you should never walk in flip-flops for a long time. You should have a rest after walking 1 hour or more, so don't wear flip-flops when traveling. In addition, it should be noted that flip-flops should be replaced after 3-4 months like sports shoes. If the sole is worn and skewed, it must be replaced in time.
Second, soak your feet with coarse salt and hot water.
If you feel particularly tired and sour after a day's running, you can add crude salt to hot water and give yourself a 10- 15 minute "foot bath", which will help relieve the discomfort of your feet, promote blood circulation of your ankles and calves, stretch tendons and improve the stiffness of your lower limbs.
Third, self-help foot massage
If you still feel sore after washing a hot foot bath, you can also do a self-help foot massage. Apply a moisturizing lotion to your hands and feet first, and then press the soles of your feet alternately with your thumb. Don't blindly massage the painful parts of your feet.
Fourth, simple "physical therapy"
For the "broken bone" disease, rehabilitation physiotherapy is always more helpful to rehabilitation than drug treatment. Here, I will teach you a simple foot movement: gently step on a small ball with your foot (tennis is enough), and gently roll the ball with the strength of your sole, so that you can massage the acupoints that stimulate your arch and stretch your calf muscles. If your symptoms are serious, it is recommended to go to the hospital for professional physical therapy to enhance the curative effect.
To sum up, flip-flops are certainly not suitable for boys of 10. Is there a problem?
