Shanghai Consumer Protection Committee: Domestic Running Shoes Are No Worse Than International Brands.

The Shanghai Consumer Protection Committee recently carried out a comparative test on running shoes sold in the circulation area of the city. The results show that although the price of international brands is generally higher than that of 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, 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.

In accordance with the relevant national standards and international standards, the project focuses on the items of folding resistance, wear resistance, cushioning, compression, resilience and skid resistance of merchants and consumers. This comparative test mainly purchased 46 samples (26 stores, 20 networks) and 23 shoes for men and women in major shopping malls, brand stores and online platforms. According to the brand, there are 29 international brands and 17 domestic brands. According to the price range, they are less than 300 yuan, 15 pieces, 14 yuan for 300-600 yuan, and 17 yuan for more than 600 yuan.

In the test of folding resistance, 3 samples of NEW BALANCE, PUMA and ASICS failed to meet the requirements of the national standard. Sole The wear resistance is an important technical index to measure the quality and durability of shoes. In this test, 1 samples of EVA wear resistance performance is general, that is, the male running shoes, which are made by MIZUNO Shanghai limited, do not meet the national standard requirements.

In the course of walking, shoes There is a friction coefficient between the earth and the earth. This experiment tests the friction coefficient to measure the skid resistance of the sole. The results show that the average slip value of the front palm is 0.375, and the best value is 0.64 (the larger the data, the higher the skid resistance coefficient, the better the skid resistance). 22 of them are higher than the average value, 24 pairs are lower than the average value (the three ranked table 4), the heel average is 0.358, the best value is 0.54, 20 of which is higher than the average value, 26 double is lower than the average value.

Shock absorption performance is an important index for running shoes to absorb impact energy and reflect the whole shoe damping effect. The test is mainly aimed at the rear part, and comprehensively compares the damping data of 46 samples, followed by Shock absorption performance The average value is 9.08, the optimal value is 4.7, and the maximum difference is 32.5 (the smaller data indicate better shock absorption performance), the difference between them is nearly 7 times. 20 of the 46 samples were available for shock absorption, of which 6 samples were above average.

The compression and springback of shoe sole is an important index to indicate whether the sole of shoes will collapse, deform and shock absorption capability after running for a long time. In this experiment, 40 samples were tested for the material and structure of the samples. The results showed that the average rebound rate was 48.52%, the best value was 29%, and the difference was 65.8%. (remarks: the smaller the percentage, the better the rebound performance). The resilience index of 19 samples is higher than the average value, of which 6 samples are higher than 60%.

According to the test results, the Consumer Protection Committee of Shanghai city gives suggestions on consumption:

1. many brands launch different products according to different arch, choose running shoes suitable for their arch type. Generally speaking, the high arch is suitable for slow shock type, low arch is suitable for control type, moderate arch is suitable for stable type. From the sole shape, generally speaking, the high arch is suitable for the curved type, the lower arch is suitable for straight type, and the moderate arch is suitable for half curvature.

2. when choosing running shoes, 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 the elasticity is better. The two is the material of the sole. PU material is the most wearable, rubber material is second, foaming material is not wearable, and the three is the pattern of sole. The pattern is dense, wide and gully, and the skid resistance is better. The four is the thickness of the sole. The thickness is thinner than that of the thin ones, and the five is the material of the upper. The running shoes of textile fabrics have better general permeability.
