Many Brands Of Famous Brands Do Not Conform To The National Standard, And Shoe Sole Cracks Appear In The Test.

Shoes of famous brand running shoes are cracked: NewBalance, PUMA, Asics and so on.

A few days ago, Shanghai Consumer Protection Committee targeted at 46 common brands in the market.

A number of comparative tests were conducted.

Reporters learned from the municipal consumer protection committee, the test results show that well-known brands such as NewBalance, PUMA, ASICS and other brands.

Does not conform to the national standard, appears in the test.

And so on.

It is said that the municipal security commission test has referred to a number of national and international standards.

Shanghai consumer protection committee revealed that the comparison test bought 46 samples, involving 29 international brands and 17 domestic brands in the city, 23 men and women styles, 26 of which were purchased through physical stores, and the 20 was purchased online.

According to many national and international standards including the "GB/T 24152-2009 basket volleyball professional sports shoes standard" and "SATRA TM144 shoe sole material testing", the municipal consumer protection committee analyzes the flexural properties, soles wear resistance, shock absorption performance and soles compression and resilience of each sample.

The test results show that the price of international brands is generally higher than domestic brands, but there is no obvious advantage in terms of quality and performance indicators.

In addition, the models sold by online shops are quite different from those of physical stores, and the quality is worse than that of physical stores.

The 4 samples that were not up to the national standard were purchased through the Internet.

The products of NEW BALANCE, ASICS and PUMA are not up to the national standard.

It is reported that according to the requirements of the national standard, in the test of folding resistance, NewBalance, PUMA and ASICS three well-known brands of running shoes test failed.

The reporter learned that the folding resistance test is simulated by walking the state of human feet, observing the cracking and degumming of running shoes after 40 thousand times of whole shoe bending. It can directly reflect the strength and toughness of the shoe side and the bottom, and the fastness of the bottom and the surrounding bars, etc.

The test results showed that the NEW BALANCE W670RG1 sneakers and ASICS's T525N cushioning running shoes had a cracking phenomenon on the sole. PUMA's 187532 men's and women's sneakers appeared at the outsole and the middle sole.

In terms of wear resistance of shoe soles, the results of MIZUNO running men's running shoes produced by Shanghai MIZUNO limited do not conform to the standard of national EVA material less than or equal to 12 mm, exceeding the standard value of 16%.

In addition, the city consumer protection committee revealed that the popular running shoes in the market are mainly made of PU and EVA material. The wearability of the PU material in the test product is better than that of EVA material.

In terms of damping capacity, 20 of the 46 samples were inconsistent in the performance of the shock absorber, of which 6 samples were significantly higher than the average value.

According to experts, damping performance is an important index for running shoes to absorb impact energy and reflect the damping effect of shoes.

The running shoes with better damping performance can not only make the weight of the human body more reasonably distributed in all parts of the foot, but also play a stabilizing role.

According to the international standard, the damping data are smaller, indicating that the damping capacity is better.

The test results show that the vibration damping value of M980RN2 men's sports shoes under NEW BALANCE is as high as 15, which is different from that of technology multilevel honeycomb particles.

PUMA's 35903503 women's sneakers are closely followed. Although they call it Trinomic mitigation technology, its damping value is as high as 14.5.

In the compression and rebound test of soles, NIKE's 705461-007 men's running shoes have a compression ratio of 66%, FILA's 22545455-GY retro running shoes, white EVA midsole compression ratio of 62%, NEW BALANCE's M980RN2 male sports shoes gray midsole compression ratio of 61%.

Experts revealed that the compression and springback of shoe sole is an important indicator of whether the sole of shoes will collapse, deformation and shock absorption performance after prolonged wear. The results show that the average rebound rate of each sample is 48.52%, and the number of well-known products is significantly higher than the average.

The city Consumer Protection Committee said that although the price of international brands is generally higher than domestic brands, there is no obvious advantage in terms of quality and performance indicators.

The high-end models of some domestic brands are not inferior to international brands in performance.

In addition, online shopping is simpler and faster than physical store purchase, but the models sold by online stores are different from those of physical stores, and the quality is worse than that of physical stores.

The 4 samples that were not up to the national standard were purchased through the Internet.

When selecting running shoes, the Consumer Protection Committee recommends that consumers can judge whether they meet the purchase needs in the following aspects:

First, the types of springback materials at the bottom.

The two foaming material is lighter than the first foaming material and has better resilience.

The two is the material of sole.

PU material is the most wearable material, followed by rubber material.

The three is the pattern of the sole.

The wave pattern with dense pattern, wide width and deep gully has better anti slip effect.

The four is the thickness of the sole.

It is thicker than thin and has poor bending resistance.

The five is the material of shoe upper.

The running shoes of textile fabrics have better general permeability.
