Running Shoes With Poor Shock Absorption Will Blacken The Brand.

Marathon and night running are the most popular sports at present. Running shoes are essential equipment. The price difference is obvious and the quality is uneven.

Yesterday, the Shanghai Consumer Protection Committee disclosed that the sampling results of running shoes in the circulation area of the city showed that the difference of shock absorption performance of the 46 samples was nearly 7 times.

The city consumer protection committee pointed out that although the price of international brands is generally higher than domestic brands, there is no obvious advantage in running shoes' quality and performance indicators.

Although online shopping is simpler and faster than physical store purchase, the models sold by online shops are quite different from those of physical stores.

4 of the unqualified samples were purchased through the Internet.

It is reported that in the shopping malls, brand stores and network platform purchased 46 samples (26 entities, 20 networks, 23 men and women shoes), the price is less than 300 yuan 15, 300-600 yuan 14, 17 yuan more than 600 yuan.

According to the relevant national standards and international standards, the emphasis is placed on the folding resistance of merchants and consumers.

Damping, cushioning, skid resistance and other items were tested.

Among them, the damping performance that plays a stable supporting role is

Absorbing energy and reflecting the effect of whole shoe damping.

The data show that the average vibration damping performance of the 46 samples 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 is nearly 7 times.

20 of the 46 samples are available for shock absorption.

Among them, Hongxing Erke, LI-NING, Jordan, noble bird, PUMA, NEW, BALANCE and other well-known brands of 6 sample indicators are higher than the average.

For the endurance performance of running shoes, 3 batches of sample shoes such as NEWBALANCE, PUMA, ASICS and other famous brand shoes appear cracking, sole opening and middle sole opening.

Mainly used PU, EVA and other materials made of different soles, wear resistance indicators are also very different.

Spot testing found that the wear resistance of PU soles is better than that of EVA material. Among them, 1 samples of EVA material wear resistance performance is general, that is, a "MIZUNO" male running shoes, which is made by Shanghai MIZUNO Co., Ltd. (the specification is J1GG152703), does not meet the national standard requirements.

In addition, the city's Consumer Protection Commission also tested the compression resilience of 40 samples. The results showed that the average rebound rate was 48.52%, the best value was 29%, and the difference was 65.8%. (the smaller the percentage, the better the resilience.)

Among them, 19 samples compression springback index is higher than the average value, among which 6 samples of Nike, Jordan, FILA, NEWBALANCE, COLUMBIA and other famous brands are higher than 60%, which are unqualified.

For running shoes, the skid resistance test of MIZUNO, Anta, 361 degree, PEAK and so on is at the end.
