baby's shoes are the necessities of daily life that mothers must identify and choose every year. What texture, sole, material, and color should be chosen, for fear that the inappropriate choice of oneself may hurt the child. However, even if the eyes are sharp, before and after comparison, it is very possible to choose the wrong one, not only has quality and safety issues, but may even contain "toxic substances."
Children's shoes become a hidden danger
In 2019, the State Administration for Market Supervision randomly inspected 90 batches of children's shoes including 90 companies, of which 15 batches of children's shoes were unqualified, and 9 children's shoes brands involved phthalates Exceeded standards, and some batches involved unqualified physical properties such as lead exceeding standards and outsole hardness. So, what exactly are phthalates? What is excessive lead? Why is there such an ingredient in children's shoes? What is the harm to the child?
01 phthalate
is a chemical additive used in the production of plastic products, which can increase the flexibility and strength of plastic, so it is widely used in toys, shoes, food packaging and other products.
Phthalates may be toxic to the nervous system of the organism. They may enter the human body through the respiratory tract, skin, and digestive tract, interfere with the endocrine system, and even cause cancer.
Studies have shown that when children are in contact with products containing phthalates for a long time, when the amount of dissolution exceeds a safe level, it will damage the children’s kidneys and liver, and even lead to testicular dysfunction and organ development in boys. Insufficiency, masculine feminization, and even premature breast development and precocious puberty in girls.
The US Consumer Product Safety Commission has clearly pointed out that since 2009, six phthalates such as DEHP, DBP, DINP, etc., are prohibited from being used in children's products, and the content must not exceed 0.1%.
The European Union proposes: children's toys, articles, clothing, such as the use of PVC materials, the six components should not exceed 0.1%, these products cover a wide range, from babies within 36 months to other age groups may be put in the mouth.
According to the relevant regulations of my country's quality inspection department: phthalates should not exceed 0.1%, but during this sampling process, some content was as high as 49%, which exceeded 500 times the safety standard.
02 lead exceeding the standard
Under normal circumstances, the lead content of children's shoes should not be higher than 100mg/kg, but in this sampling, the non-compliant children's shoes will reach 400mg/kg. If you wear these unqualified children's shoes every day, once you consume too much The lead content is likely to affect brain development, damage kidney function, and even cause anemia, high blood pressure and other diseases.
WHO also clearly stated: Lead is the most serious toxic chemical substance for children, especially children under 3 years old.
03 physical properties are not up to standard
sole thickness, sole hardness, sole height, abrasion resistance, comfort, etc. are all factors that qualify the physical properties. If the child wears unfit, uncomfortable, and hard shoes for a long time, it is easy to cause valgus thumb, flat feet, and internal horoscope during activities and play.
04 Toluene formaldehyde
children's shoes if the material and glue used in the bonding process exceed the standard formaldehyde, plus the baby is low, the breath of the mouth and nose are close to the shoes, it is easy to breathe into the baby's body, causing baby discomfort.
How to choose children's shoes
When choosing children's shoes for your baby, it is best to choose a cloth material with good air permeability, because the baby sweats a lot, which facilitates their exercise to dissipate heat. At the same time, pay attention to the following aspects.
01 Touching the soles
soles are to protect our feet from being hurt by sharp objects, and to protect us from a certain buffer zone when we walk, which can protect our knees. Try to choose soft shoes for your baby, which means that the soles are softer at one-third of the soles, easy to fold, which helps stabilize their arches and facilitate the normal development of their feet.
02 Look at the color
The main function of formaldehyde is to prevent discoloration. It is easy to add a large amount of formaldehyde dyeing auxiliaries to the colorful and rich fabrics; and the more and larger the pattern, the more formaldehyde content. Once these contents exceed the standard, it will cause children's allergies and damage the respiratory system. Therefore, when choosing children's shoes,Try to choose a single color and few decorations to reduce the probability of your baby eating by mistake.
03 Smell
If there is a pungent smell, you must first eliminate it. It is best to choose shoes from a regular manufacturer to see if the various signs are complete, and avoid buying shoes made of recycled materials.
These four types of shoes are best not to be
. The following four types of shoes are best not to be selected for your baby. Each has its own disadvantages:
called
children will follow the ground unconsciously in order to walk, which will affect the spine for a long time. At the same time, the sound of calling shoes is harsh, which can easily damage the baby’s hearing.
Flash shoes
will emit colored light when stepping on, which can easily stimulate the baby's vision. Frequently facing flashes can cause frequent blinking, fatigue of eyesight, and decreased vision and color sensitivity.
Too thick soles
too thick soles are not conducive to the baby's perception of the ground conditions, easy to fall; and will cause the child's center of gravity to move upwards, the entire foot muscles are in a tight state, long time will cause bone deformation.
Second-hand shoes
Shoes worn by others will have different stress points, and there will be bacteria that are not clean.
