the reporter came to a brand store in Nanjing West Road, which was called "a href=" http://www.91se91.com/ "target=" _blank "shoes < /a" yesterday. A smell of similar rubber can be seen in the shop, and the walls are covered with a variety of different styles of "hole shoes". At this time, several consumers are trying on them.

Random look at the label of the shoe. It is indicated above that the main component of the shoe is ethylene vinyl acetate copolymer (EVA), which is produced in Guangdong.

The price is mostly around four hundred yuan.

"These shoes are made of resin. Things are definitely different. There's a big difference in materials before they're done."

A salesperson said.

to further understand the material and supervision process of the brand, the journalist contacted the brand public relations department later, but until the deadline, no reply was received.

reporter then searched Taobao keyword "hole shoes" on Taobao website, showing up to more than 37 pieces of goods.

At the same time, the price difference also appears here. A new shoe priced at 469 yuan in the exclusive store is priced at 65 yuan in an online shop with orange / blue color. The price is only 1/7 of the former.

Another pair of Tibetan Blue / red matching shoes with a price tag of 399 yuan is only 12 yuan online, and the difference between them is 32 times.

"The shoes are also made of resin, and there is no difference in wearing feeling."

A shop owner introduced.

However, when the reporter asked whether the material would be harmful to the human body, the store only said, "wearing a foot is absolutely fine."

Mr. Gao has bought a pair of "cave shoes" at a price of 19 yuan. He recalled that after buying shoes, there was only one rough printed "certificate", but he could not find any manufacturer's name.

And when he approached his shoes with his nose, he could smell a pungent taste.

"After a month, the taste is still very strong, and then I will no longer wear it."

in fact, many cheap "hole shoes" on the market are not only cottage products, but also exist in materials.

"Driven by interest, inferior recycled plastics are used instead of resin materials.

It's not surprising that it tastes heavy. "

An insider told reporters.

professor Yu Shanhui of the Department of organic chemistry of East China University of Science and Technology told reporters that as the polymer copolymer has good chemical stability and ethylene vinyl acetate copolymer is non-toxic, it is relatively safe for human body, especially the products produced by regular manufacturers, and should be safe to use.

But those cheap "hole shoes", manufacturers to reduce costs, will use plastic instead of the original EVA material should be used, or even recycled plastic from low-grade plastic to make recycled plastic, in the process will also add formaldehyde and other chemical raw materials.

The hole shoe made of these materials will produce pungent odour, and the specific formaldehyde content will also be different because of the different craft of the manufacturer.

but Professor Yu said that although polycyclic aromatic hydrocarbons are carcinogenic substances, it is not so easy to enter the human body through skin after direct contact with their feet. Users should be more careful about formaldehyde.

"Most of the chemical poisoning is absorbed by the lungs, but once the inferior plastic shoes are decomposed, such as the continuous high temperature during this period of time, the shoes will be released at different temperatures after being exposed to high temperatures for a long time, and will be absorbed by the body in the form of gas.

and for what the media said before, by wearing socks to prevent harmful chemicals, Professor Yu admitted that to a certain extent it could be better, but a better way is to wear less or not wear those inferior hole shoes as little as possible.

national standard has been formulated and will soon be implemented .

compared with other kinds of < a href= "http://www.91se91.com/news/list.aspx? ClassId=101112104106" > shoes < /a >, "cave shoes" can only be regarded as "new classmates". Is there a standard for this kind of shoes?

"P" reporter called the national footwear Standardization Committee, the staff said, "cave shoes" in the reference standard should belong to plastic shoes.

Accordingly, the reporter found on the website of the National Standardization Management Committee that there is no specific national standard for plastic shoes at present, but only the entry exit inspection and quarantine industry standard.

in the name of "SN/T code of footwear inspection third part: plastic shoes" (1309.2-2010), there are certain requirements not only for the physical properties and appearance quality of footwear, but also for inspection of toxic and harmful chemical substances in the inspection items.

However, this standard applies only to plastic shoes imported and exported, not domestic plastic shoes sold domestically.

a related person said that at present, the < a href= "http://www.91se91.com/news/list.aspx ClassId=101112104106" > shoes > /a > standard used for daily wear in China is mostly recommended by chemical industry or light industry, which only requires appearance and physical mechanical properties, and there is no strict requirement for the limit of harmful substances.

It is understood that the new national standard "limited substances in footwear and footwear components" (GB/T 29292-2012) has been released at the end of last year.

Among them, the items for controlling harmful substances in footwear should be controlled as follows: Ph value, free formaldehyde, decomposable aromatic amine dyes, extractable heavy metals, color fastness to rubbing of shoe and inner bottom, etc.
