Flip-flops
Shorts T-shirts and flip-flops are the most serious choices. In fact, like T-shirts, flip-flops are also a "democratic" element in fashion. The sense of design lies in the pattern, design and color, which has little to do with the wearer's body shape. As long as the flip-flops themselves are well designed, no matter how tall or thin, they can wear styles-unlike big-name clothes.

In fact, don't think that flip-flops can only match the casual style of beach clothes. The slim feeling of men's fashion has also made flip-flops. Because stovepipe pants emphasize the sense of lines, if paired with leather shoes or sneakers, it is best to have a slim shoe type, otherwise it will be like a toothpick inserted in steamed bread. And how can a slim shoe shape keep the line feeling of stovepipe pants better than a pair of bare feet? Flip-flops come at the right time, and two simple and eye-catching buckles are really a good choice for slimming.

When choosing flip-flops, we should also pay attention to either going to extremes in fancy, which is most suitable for beach casual wear, or it must be solid colors, such as black, silver and brown, full of low-key sense of low technology and high-level sense. In the early years, "flip-flops" only belonged to some cool little boys. This kind of cool and convenient slippers has been worn on the feet of many fashionable girls, and the styles are more abundant. However, experts warn that women wearing flip-flops should be careful to dress up as "inner figures". Researchers at Auburn University in the United States found that flip-flops can hardly provide any support for the feet. Wearing them will gradually change a person's walking style and stride, and eventually lead to serious problems in heels, soles and ankles.

A doctor explained that when walking in flip-flops, because the only strap between the toes can't give the foot enough support surface to lift the slippers, every time the heel leaves the ground, the toes will bend upwards and "hook" the slippers, which is an unnatural force application situation. If the time is too long, it will cause the muscles in front of the calf to feel sore. In order to avoid the embarrassment of losing shoes, we should shorten the stride and turn our ankles inward, which is what we often call the "inner character". When walking in flip-flops, people's center of gravity will tilt forward, their knees will naturally bend slightly, and their lumbar vertebrae will bend backwards. Over time, both knees and lumbar vertebrae will hurt. Women who like to wear flip-flops often have heel pain and even heel spurs. Sun Wei pointed out that the culprit of this problem is the sole of flip-flops. Wearing high-heeled shoes for a long time, hard or uneven soles and excessive heel load can easily lead to plantar fascia inflammation and heel pain. At the end of the summer vacation, students returned to school one after another, and the number of people who went to the school hospital for treatment because of leg pain and foot pain increased greatly. This phenomenon has attracted the attention of Professor Wendy Weimer. She is an associate professor of biomechanics at Auburn University and director of the Biomechanics Laboratory. She found that most of the shoes worn by students with leg and foot pain in summer are flip-flops. Going back to school in autumn, changing online sneakers or street shoes, my legs and feet are strongly uncomfortable.

Under the auspices of Professor Wendi Weimer, students of Biomechanics Department set up a research group on flip-flops. The group gathered 39 volunteers, both male and female, aged between 19 and 25. In the experiment, volunteers will walk in running shoes and flip-flops. In order to make the data as objective as possible, the flip-flops provided in the experiment came from different manufacturers and retailers, and the prices ranged from $5 to $50. Similarly, running shoes come in many different prices and designs. Volunteers participating in the experiment will put sensors on their backs, hips, calves, ankles and feet. There is a platform on the ground. When the foot steps on it, the data of vertical force on the foot will be recorded at the moment when the foot touches the surface of the platform. At the same time, the movement posture of the experimenters when they walk, as well as any subtle movements of their hips, legs, ankles, feet and toes are recorded by the video system.

The experimental report points out that when people wear flip-flops, they walk with smaller steps. This leads to more stress on the body, because you have to take more steps for the same distance. This means that muscles and joints will suffer more wear and tear. Everything comes from a tiny movement of the toes when walking. When wearing flip-flops, people are worried that shoes will fly off, so they will consciously bend their toes to grab the soles when walking.

"The body is a precise and wonderful machine. When you exercise a certain group of muscles, it will be implicated in the movement of other groups of muscles. Tightening the muscles of the toes will cause the muscles that pull the toes up to stop moving. This means that you can't lift your toes high enough when you walk. " This is a chain reaction. Because the shoes are pinched, the toes can't be relaxed and lifted, which leads to a large angle of ankle joint change and a small vertical stress on the heel. Therefore, when the same experimenter wears flip-flops, his stride is smaller than when he wears running shoes. "The change of stride will lead to a series of changes in the body's power chain. Starting from the soles of the feet, it extends to the ankles, calves, knees, hips, back and extends to the whole body. " Schloyer said. Bending your toes and grasping the soles of your feet will lead to excessive use of plantar aponeurosis and connective tissue from toes to heels, leading to inflammation of soles and heels, and even pain in hip joints and back. "Buckled sandals are a healthier choice because your toes don't need to bend and tighten your shoes to prevent them from flying away. These shoes can also provide better ankle and heel protection. " Schloyer said.

Schloyer, who also owns two pairs of flip-flops, said: "The experiment doesn't recommend that people never wear flip-flops, but they can't wander around all day. And like running shoes, it will be changed in three to four months. " Achilles tendon, English is Achilles tendon, Achilles heel in Greek mythology. Achilles tendon connects the end of fibula muscle with calcaneus. When we walk, the calf muscles contract, and the Achilles tendon helps them pull up their heels and leave the ground. Walking in flip-flops requires more strength to lift the heel, which leads to the demand for achilles tendon and prone to achilles tendinitis. 1, internal pain, pain, tenderness and stiffness of achilles tendon can occur in any part of achilles tendon. Pain usually occurs in the early morning or at rest after strenuous exercise.

2. There will be intense pain or tenderness when the two tendons are squeezed.

3. When the lesion gets worse, the tendon will swell and nodules will appear in the lesion area. 1, paparazzi-ridden star: When a star reaches the level of Faye Wong, paparazzi follow him as soon as he goes out. People who are going fast everywhere are the last people to wear flip-flops, but these people love flip-flops most, and they are simply the spokespersons of flip-flops. Faye Wong loves to wear flip-flops in winter and summer. She is the best example of flip-flops fashion and a representative of being hurt by flip-flops. She doesn't need to go to Emei Mountain for advice. Because she wears flip-flops, Faye Wong's ankles, calves, knees, hips and back are all black spots of her health.

2. Pregnant women and overweight people: Overweight people need the support of shoes more, and they usually put more pressure on their feet, ankles and back caused by obesity. And flip-flops will aggravate the loss of these positions and bring more harm to these parts.

3. Shoe thrower: Paris Hilton's sister Nicky often wears flip-flops when she goes shopping in summer, but once she threw flip-flops on her left foot while shopping, which made the paparazzi next to her laugh. In fact, sandals are easily dumped, and flip-flops are more easily dumped. To ensure that you don't get dumped, you can only clamp it hard, which will easily hurt your achilles tendon. Therefore, those who are easy to reverse their shoes are not suitable for wearing flip-flops, and their image is ruined.

4. People who need special care for their feet: Athletes who advertise by their beautiful legs, such as Lin Chi-ling, and those who compete by their feet, such as Ronaldinho and Yao Ming, should not wear flip-flops. Flip-flops will increase the chances of sprains and falls, which is of great significance. Look before you leap. Some British experts warn that wearing thin and fragile toe caps will increase the risk of skin cancer. The thin straps on the shoes expose the fragile skin on the feet to the sun, and few people will apply sunscreen on their feet. According to Sing Tao News Group, Anthony Canto, a British foot surgeon, has been urging women to wear high-index sunscreen on their feet or shoes to cover them. Cantu said that foot canceration such as black spots or lumps is often ignored or misdiagnosed as a minor illness. "The skin on the feet is very sensitive to the sun, because it is very thin, and there is no clothing protection all year round, unlike the arms being blocked by sleeves from time to time." Kangtu said: "Many people have gradually realized that they should always check some parts of their bodies for suspicious lumps, but few people check their feet." Skin cancer often appears on the soles of feet, the surface of feet, between toes and under nails. The most fatal precancerous symptom of skin cancer is the change of mass, such as itching or bleeding. In the past three months, at least two cases of skin cancer caused by sun exposure have been diagnosed in the Northwest Clinic where Dr. Kangtu works.

John, spokesman for the British Skin Foundation, said: "We always neglect our own feet. In fact, because our feet land horizontally, we receive more vertical ultraviolet rays. " (1) The soles of flip-flops are spongy and can't give our feet arch support. 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 radian, which can help us to cushion the vibration when walking, while flip-flops are just like walking without shoes, which can't meet the radian of soles and can't give enough support to 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 the toes. When walking, the feet can't give enough support to lift the slippers, so they can only "clip" two straps by the strength of their 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 can tighten the achilles tendon and even hurt the foot bone. 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) Flip-flops have no support for ankles. 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 sclerosis 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) 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.
