Domestic Running Shoes Vs International Brand Comparison Results Surprise

Many people feel that foreign goods are better than domestic products. But recently, the Shanghai Consumer Protection Committee has carried out a comparative test on the running shoes sold in the circulation area recently. 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 in physical stores. quality Worse than the entity store. The 4 samples that were not up to the national standard were purchased through the Internet.

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 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.

In the test of folding resistance, 3 samples of NEW BALANCE, PUMA and ASICS failed to meet the requirements of the national standard. The wear resistance of soles 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 requirements of national standards.

Shock absorptive performance is the absorption energy of running shoes. Whole shoe reduction The important index of earthquake effect. The test is mainly aimed at the rear part, and compares the damping data of the 46 samples. The average value of the rear shock absorber is 9.08, the optimal value is 4.7, and the worst value is 32.5 (the smaller the data indicates that the shock absorption performance is better), the difference between the two 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%.

In the course of walking, there is a friction coefficient between the shoes and the ground. This experiment tests the friction coefficient to measure the skid resistance of the sole. The results showed that the average skid resistance coefficient of the front palm was 0.375 and the best value was 0.64 (the larger the data, the higher the skid resistance coefficient, the better the skid resistance), 22 of which was higher than the average value, the 24 pair was lower than the average value (ranked three in the table 4), the heel average was 0.358, the best value was 0.54, 20 of which was higher than the average value, and 26 pairs were lower than the average value.

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, and the lower arch is suitable. Straight type 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.
