Are the shoes you buy for your child really safe?
Children's shoes are a necessity for every family with children, but in recent years, more and more "poisonous children's shoes" have been exposed by CCTV, and if you choose badly, it will not only affect children's foot development, but also lead to problems such as precocious puberty, so how should we distinguish and choose when buying shoes? Come and come, pay attention to the passers-by, listen to the guests.
"Poison Shoes"
"Toxic children's shoes" is simply unqualified shoes, the mainland children's shoes market is large, since 2014, the mainland quality supervision department will have a relevant sampling inspection for children's shoes every year, inspection items and the corresponding results will also be reported by CCTV.
CCTV has repeatedly reported unqualified batches of children's shoes:
In 2018, according to the results of the random inspection of children's shoes by the Shanghai Quality Supervision Bureau, 12 batches of 40 batches of children's shoes were unqualified, and the failure rate reached 30%.
In June 2022, the Shanghai Quality Supervision Bureau once again announced the results of random inspections of children's shoes, and 48 batches of 200 batches of children's shoes were unqualified, with a failure rate of 24.5%
In December 2022, according to the results of the random inspection of children's shoes released by the Jiangsu Quality Supervision Bureau, 10 batches of 100 batches of children's shoes randomly inspected were unqualified, with a failure rate of 10%.
In addition to these reported by CCTV, many places have also announced the results of sampling inspections for children's shoes:
In 2021, the Beijing Market Supervision Bureau conducted random inspections of children's clothing and children's shoes, and the results showed that 20 groups of clothing were unqualified and 26 groups of children's shoes were unqualified.
In June 2021, the Fujian Regulatory Bureau announced the results of sampling 30 batches of children's shoes, showing that 6 batches were unqualified, with a failure rate of 20%.
In January 2021, the Hainan Regulatory Bureau announced the results of sampling inspections for children's shoes in the second half of 2020, and 8 batches of 30 batches were unqualified, with a failure rate of 26.7%.
In recent years, coupled with the opening of the mainland's two-child policy, the demand for children's shoes has increased, with an annual demand of about 1.7 billion pairs. Children under the age of 16 on the mainland account for about a quarter of the total population, and if this demand and the 30% failure rate are measured, every child may wear a pair of substandard children's shoes every year.
What are the dangers of wearing substandard shoes frequently?
According to the test results, the unqualified items include heavy metal content, phthalates, wear resistance, sole hardness, etc., among which the main ones that affect health are heavy metals and phthalates. Heavy metal detection is mainly to look at the content of heavy metals (lead, chromium, arsenic) in children's shoes, usually some manufacturers in order to arouse the love of children, will make the color of shoes more vivid, and these colorful dyes are the source of heavy metals, but also the source of phthalates.
Heavy metals are generally more than lead and chromium components, and excessive lead may damage the nervous system and affect children's growth and intellectual development. Chromium generally refers to hexavalent chromium, which is any compound containing chromium in the oxidized state +6, which has many uses and is commonly used as a dye in the production of children's shoes. However, due to the oxidation of hexavalent chromium, it is toxic and carcinogenic, not exceeding the standard is fine, once it exceeds the standard is very harmful to health, if inhaled it will cause lung cancer, long-term exposure may also cause cancer, especially children are easy to get sick from the mouth.
The second is phthalate, which is a chemical used to soften plastics and increase plastic plasticity, and its uses are very wide, such as children's toys, detergents, hairsprays, shampoos, personal care products, electronics, building materials, medical devices, paints, inks, pharmaceuticals, textiles and so on. Even the food packaging field has their existence, known as "ubiquitous chemicals", in children's shoes it mainly plays a role in softening and enhancing elasticity.
There is no problem with normal use of phthalates according to standards (China stipulates that in toys and child care articles, the content of phthalates should not exceed 0.1%), but once exceeded the standard, the damage to the human body is irreversible. Studies have shown that phthalates play a role similar to estrogen in the human body and animals, can interfere with endocrine, it can enter the human body through the respiratory tract, digestive tract and skin and other ways, long-term exposure can cause polyneuritis, numbness and other symptoms, serious affect the kidneys, brain, development, resulting in precocious puberty in children.
Some businesses will add too many phthalates in order to make the sole softer, resulting in excessive content, and the content of phthalates in the outsole produced by a Fujian shoe company exceeded the standard by 470 times.
How to choose children's shoes?
Through data surveys, more than 25% of children in Shanghai have foot abnormalities, including flat feet, hallux valgus, internal and external eight and other problems, of which shoes account for a large part of the reason, inappropriate shoes can easily affect bone development, so how should we choose?
When choosing shoes, do not take the price as a standard of measurement, some well-known big brands have previously announced unqualified batches, such as a certain tai, ba bean and so on. You can choose the right shoes by the following methods, first of all, look at the hardness of the sole, many parents will have a misunderstanding when choosing shoes, that is, think that the softer the sole, the better, but in fact, too soft soles are not suitable for children to wear, the hardness of the sole can affect the child's gait mechanism, the sole is harder to help control the hind foot valgus, too soft sole will also have an impact on bone development.
The hardness of the test sole can be judged by the three steps of "folding, pinching, twisting", folding the sole, soft and hard shoes will be bent at 1/3 of the shoe, if the toe is bent too much, it is unqualified; Pinch refers to pinching the heel of the shoe and the front head with both hands, which needs to have a certain hardness, and do not choose the softer one; Finally, you can twist the shoes with both hands to see if the shoes will be deformed.
The second is to look at the color, material and smell, do not choose the color is too bright and pungent. Finally, pay attention to the following kinds of shoes that are not suitable for children do not choose, one is cave shoes, there have been incidents of children getting stuck when they sit on the escalator, and the sole of cave shoes is relatively soft, which has an impact on foot development.
The second is jelly shoes, which are usually made of PVC, with poor air permeability and poor slip resistance; The third is "flash shoes", in recent years, a kind of shoes with a glowing sole on the market have been popular with children, but this kind of shoes are a potential safety hazard, and some luminescent principles are placed in the sole of the LED light strip, if the failure is serious, it will spontaneously combust. Earlier, when a Canadian mother celebrated her son's birthday, the shoe cabinet suddenly caught fire, and the cause of the fire was this pair of glowing shoes.
