The flip-flops wear the injured legs for a long time.

(1) The sole of the flip-flop is a sponge texture, and we cannot give our feet an arch support.
The bottom of the flip-flops may look very soft and comfortable, but most of the flip-flops are designed to be completely flat and very thin, and your feet will eventually collapse excessively. Normal people’s soles have a certain curvature, which can help us to cushion the vibration when walking. The flip-flops are like walking without touching the shoes. They can not meet the curvature of the soles of the feet, and can not support the feet enough. This can cause pain in your heel, arch, and toes. Flat shoes that are too flat are also easy to hurt for this reason, not as comfortable as they look.
(2) They will make your muscles and tendons overwhelmed.
Flip-flops do not have a complete shoe design. There are only two thin straps or only one V-shaped belt that straddles your toes. When walking, you can’t give enough support to lift the slippers, only rely on the strength of the toes. “Clip” the two straps. When you are walking, you are finally lifting your toes so that the muscles and tendons have to do all the work. In order to hold the shoes more firmly, the toes will unconsciously tighten for a long time and will be twisted to “grab” the soles. This twisted state lasts for a long time, causing strain on the tendons under the toes, and even nerve inflammation.
(3) Flip-flops will make the Achilles tendon, and even the foot bones injured.
If you are used to wearing high heels, flip-flops may eventually stretch the calf muscles. The human foot bones are usually relatively short and not easy to be injured, but one-third of the front part of the sole has a row of a relatively slender phalanx, which is not so “strong”. The lack of protection of the toe is greatly increased by the flip-flops, which greatly increases the pressure on the arch of the foot and the surrounding ligament tissue. In addition to causing inflammation, it can also cause pressure fractures of the phalanx.
(4) The flip-flops have no support for the ankles.
In the summer, because people love the flip-flops, spraining the ankle becomes common. Moreover, when wearing a thin-bottomed flip-flop, the body’s center of gravity will tilt forward unconsciously, greatly increasing the pressure on the ankle, which may easily lead to sprained muscles of the calf and plantar fasciitis. In the long run, between the ankle and the bone of the knee. The cartilage tissue will also be degraded, leading to the appearance of bone hyperplasia and even bone spurs.
(5) They can cause the skin to harden and the heel to split.
The constant tapping of the shoes on the back of the soles will make your skin harder because your feet will be exposed to the air and the skin will become dry. If it gets too dry, dry and hard skin will crack and bleed, which must be very painful.
(6) They also cause pain in the hips and waist.
When wearing flip-flops, you often unconsciously change your gait, the frequency becomes faster, the steps become smaller, and this way of walking can easily cause pain in other parts of the body. The flip-flops are very difficult to follow, so in order to avoid the shackles of the shoes flying out with the feet, we often deliberately shorten the pace and turn the ankles inward to “bar” the shoes, and the body is leaning forward, knees will Naturally curved, the spine of the waist will also bend, for a long time, not only will your step become a childish “inner character”, knee and spine will be painful, and even cause sciatica and other problems.
(7) The feet are more susceptible to trauma.
When people walk on the gravel road and on the muddy road, the flip-flops are not guaranteed. Recall that when you wear flip-flops, are you more cuts, stabs, and bruises? Sandals with buckles are a healthier option, not only do your toes need to bend your shoes to keep the shoes from flying off, but also provide better ankle and heel protection.
