During pregnancy, the weight of pregnant women generally increases by about 15 kilograms. When walking, the pressure on the legs and feet is much greater and the center of gravity is also changed. Wearing a pair of unsuitable shoes can make the pregnant woman feel tired and affect the development of the fetus in the abdomen. . The flexibility of the foot is mainly achieved by the arch of the foot. In addition to absorbing the shock of the human body walking, the foot arch can also maintain the balance of the human body.
And many women are pregnant for about 3 months, the toes begin to swell; about 6 months of pregnancy, the foot edema is more obvious; on the eve of childbirth, the edema of feet and legs is quite prominent. The amount of foot circumference change (swelling) in the day is between 10-25mm, far exceeding the tolerable range of human feet. The change in maternal foot shape is limited to changes in circumference (fat), and the change in foot length is a change in weight (ie, sitting, standing and walking), and the average of sitting and standing. The variation is about 4-7mm, and the average change in standing and walking is about 3-6mm. For normal people, under the condition of an average daily shoe-keeping time (8 hours), the best tolerance for foot circumference or slightly fatness is 3-5mm.
Therefore, pregnant women during pregnancy, especially during the third trimester of pregnancy, the demand for special footwear for pregnant women is very important. At present, the shoes worn by pregnant women are mainly flat leather shoes:
One is a slipper. Its health hazard is the poor anti-slip function of the sole, which can easily lead to twisting, falling, etc., which seriously endanger the health of pregnant women and even lead to premature birth and abortion. Because pregnant women during pregnancy, the weight of the body generally increase about 15 kg, when walking on the legs and foot pressure is much greater, the center of gravity has also changed. Another point is that pregnant women sweat glands exuberant, sweaty feet, easy to form Sweaty feet may cause dermatitis when wearing rubber or plastic slippers. It is particularly evident in pregnant women with allergic constitutions. When dermatitis is only onset, it is only redness of the instep and may feel itchy, so many people mistakenly believe that it is “foot rash†or “eczemaâ€. . And if the slippers are worn for too long, the bottom position will become depressed, and pregnant women will feel fatigued as if they did not wear shoes and walk on a hard and hard ground, thereby damaging the development of pregnant women.
The second is sports and casual shoes. The design of ordinary casual shoes cannot be suitable for the changes in the shape of the pregnant woman's foot, and therefore it is extremely uncomfortable to wear. The impermeability of sports shoes made of poor materials will also increase the swelling of the feet. Therefore, try to avoid wearing synthetic shoes or shoes made of nylon leather. The long-term pregnant women wearing flat shoes, usually the first landing on the heel and the foot after the ground, wearing flat shoes can not maintain the shock absorption of the arch, but also easily lead to muscle and ligament fatigue and injury is not conducive to the growth of pregnant women. And after birth there will be sequelae of postpartum low back pain.
The third is leather shoes, but its ventilation is poor. The sweat emitted from the feet after walking can not disappear in time, especially in the sweaty feet. This gives anaerobes and molds a good growth and breeding environment. Therefore, it is not surprising that wearing boots is easy to get beriberi. In addition, because pregnant women have swollen feet and become more sensitive to leather, it is very easy for pregnant women to feel that their feet are hardened, which is not conducive to the walking of pregnant women. The sequelae of waist and leg pain will appear after birth.
Therefore, pregnant women in the selection of shoes, in addition to pay attention to comfort, warm, but also must take into account the need for arch. Because the flexibility of the foot depends mainly on the arch. In addition to absorbing shocks when walking, the arch can also maintain balance. Therefore, high-heeled shoes and fully flat shoes are not suitable for pregnant women, and about 2 cm in height, flexible, loose uppers made of soft materials, followed by relatively large and solid shoes are the best choice for pregnant women.
