The danger of flip-flops

[This site - shoes and life] summer, many friends like to wear flip-flops to work, shopping, vice president of the First Affiliated Hospital of Jinan University, orthopedic expert Professor Cha Zhengang and other orthopaedic experts advise that long time wearing flip-flops will be Damage to bones and joints, especially in pregnant women, can also cause serious consequences such as miscarriage.

Long-term wearing flip-flops harm

For the popular flip-flops, Professor Zhen Zhenang said: flip-flops do not meet the human biomechanics, when wearing, it is easy to bring the body's extra body incoordination, over time, will have foot fatigue, The fatigue of the waist causes early pathological changes in each joint.

Professor Cha Zhengang pointed out that the foot of the human body has arches, which are divided into forefoot and hindfoot. After the foot is also called the heel, the front foot is also called the foot. The normal stress point of the human is in the first and fifth metatarsal parts of the forefoot, together with the posterior calcaneus, to synthesize three-point movements and to form elasticity through the arch of the foot. "Flip-flops because of the special structure, the upper has only one clip to connect the foot and the upper. When wearing flip-flops in the summer, because the soles are prone to sweating, the foot can easily slip with the upper when it is moving. In order to maintain the body's relative stability, the toes and inner muscles of the foot are over-contracted when walking, and the second, third, and fourth folds of the original unforced force are added to the force. It is prone to fatigue, causes foot pain, or even causes membrane syndrome.When the flip-flop is worn for a long time, because of abnormal walking posture, the knee joint is abnormally stressed, the waist is not coordinated, and it is easy to cause softness of the foot and stiffness of the psoas. It is a prelude to the transformation of the function of the knee and the waist."

Foot pain, spinal ankle shoes are mostly unwell

Prof. Zhenao Zhen reminded that many people who walk for a long time will feel foot pain and spinal anesthesia. Except for the foot itself, most of the problems are caused by the uncomfortable wearing of shoes. The principle of the human body walking is: when the right foot is on the move, the stress point is on the left foot. The walking force of the person mainly depends on the arch of the arch. Because the shoes are not suitable for wearing and the force point is displaced, they will inevitably cause excessive load on the joints. Causes tiredness of the plantar muscles, and even makes the bottom of the foot "corn". "The shoes of the 'flip-flops' type are mainly worn for leisure and convenience and should not be worn for a long time."

For those who often wear "flip-flops", how do you judge the need for treatment or how to change shoes?

Professor Zhenao Zhu said that the long-term environment and bad habits are easy to cause diseases, which has a greater relationship with time. Occasionally wearing 'flip-flops' will definitely not be a problem. However, long-term wear can easily cause related osteoarthritis. If you have already developed the above symptoms, you must pay attention to it and replace the appropriate shoes. If the situation is serious and you cannot get relief after changing your shoes, you should look at an orthopaedic surgeon.

Pregnant women wear flip-flops prone to placental abruption

Pregnant women are prone to bloated feet, so many mothers prefer to choose convenient and comfortable flip-flops. For this choice, Prof. Zhen Zhenang specifically reminded: Because of the structural problems of the flip-flops, the soles and the uppers are subject to unstable forces and are prone to slip. In order to avoid falling, the human body produces natural forward or backward protection. Action, easily lead to excessive contraction or stretching abdominal muscles, pregnant women can easily cause placental abruption, and even miscarriage, "I suggest pregnant women try not to wear flip-flops."

Special people need to choose special shoes

The choice of shoes not only affects the joints of the foot, but also affects the health of the waist. Professor Zhenao Zhu reminded that for the general population, choose comfortable, moderate-sized shoes. Shoes that are too big and too small, in addition to being unfavorable for walking, can affect foot health more or less. “Especially for some special groups with foot defects, special attention is needed, and more targeted shoe selection is needed. For high arch feet less than 120 degrees, it is necessary to wear relatively soft soft shoes. For arches greater than 120 degrees The flat feet should be chosen to have tough shoes with relatively thick soles and slightly arched shoes."

Professor Zhenao Zhu suggested that for the purchase of special shoes, it is best to consult an orthopaedic specialist and go to a professional institution to order or purchase, which is more conducive to the health of the foot. (Cooperative Media: Garment Collocation)
