Is there any harm in wearing those Japanese slippers? You know, shoes with something between the big toe and the second toe.

As for cancer, that's impossible. Seven deadly sins of foot injury caused by flip-flops.

Flip-flops should not be worn for a long time.

1. The soles of flip-flops are spongy and cannot support our feet and arches.

The soles of flip-flops may look very soft and comfortable, but most flip-flops are completely flat and very thin, and your soles will eventually sink excessively. Normal people's soles have a certain curvature, which can also help us cushion the vibration when walking. Walking without shoes is like touching the ground directly, which can neither meet the radian of the sole nor give enough support to the feet. This may cause pain in your heel, arch and toes. Taiping flat shoes are also easy to hurt their feet for this reason, and they are not as comfortable as they look.

2. They will crush your muscles and tendons.

Flip-flops have no complete shoe design, only two thin straps, or only one V-shaped strap across your toes. When walking, you can't give your feet enough support to lift the slippers, so you can only "clip" the two straps by the strength of your toes. When you walk, you are the last person to lift your toes, so that your muscles and tendons can do all the work. In order to hold the shoes firmly, the toes will unconsciously tighten for a long time and curl up to "grasp" the soles. This twisted state lasts for a long time, which will lead to tendon strain under the toes and even nerve inflammation.

3, flip-flops will make the achilles tendon tight, and even the foot bone is injured.

If you are used to wearing high heels, flip-flops may eventually overstretch your calf muscles. People's foot bones are usually thick and short, which is not easy to be injured, but there is a row of slender phalanges in the first third of the sole of the foot, which is not so "strong". Flip-flops lack the function of protecting toes, which greatly increases the pressure on the arch of the foot and its surrounding ligament tissue. In addition to causing inflammation, it can also lead to stress fracture of phalanges.

4, there is no support for the ankle.

In summer, sprained ankles become common because of people's love for flip-flops. Moreover, when wearing thin-soled flip-flops, the body's center of gravity will unconsciously lean forward, which will greatly increase the pressure on the ankle and easily lead to calf muscle sprain and plantar fasciitis. In the long run, the cartilage between the bones of the ankle and knee will also degenerate, leading to bone hyperplasia and even the appearance of bone spurs.

5. They can cause skin hardening and chapped heels.

Shoe slapping the back of the sole of the foot will make the skin hard, because the foot will become dry when exposed to the air. If it becomes too dry, the hard skin will crack and bleed, which must be very painful.

6. They can also cause hip and waist pain.

When you wear flip-flops, you often change your gait unconsciously, and the frequency becomes faster and the number of steps becomes smaller, which is easy to cause pain in other parts of your body. When flip-flops are worn, they don't follow the feet, so in order to avoid the embarrassment of shoes flying with the feet, we often deliberately shorten the pace and turn our ankles inward to hold the shoes. Moreover, when our body leans forward, our knees will naturally bend, and the spine at the waist will also bend. Over time, not only will your steps become childish, but your knees and spine will also be painful and even cause sciatica and other problems.

7. The feet are more vulnerable to trauma.

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.

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.

Teach you four tricks to protect your feet

Pay attention to protect your feet in summer.

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, 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. Don't worry, but it's also harmful. Wear at most 1 hour.
