Running Shoes Can'T Hurt Your Feet.

Appropriate Running shoes It can provide good cladding and stability, let feet contact with the ground, move horizontally, or when the road surface is high or low, it is not easy to shake around and reduce the possible injury. The good shock absorbability and elasticity can absorb the impact from the road surface, and then protect the feet, ankles and knees. At the same time, the legs can be effectively transmitted to the road surface and improve the running efficiency.

Air permeability is also important for long-distance runners. Running shoes In constant motion and friction, the feet will expand and the temperature inside the shoes will also increase. If the heat is not effective, it will be very uncomfortable for the feet.

For runners who have long-distance running habits, the consumption of running shoes is staggering. The durability of running shoes affects not only the problem of sole wear, but also the midsole. body The structure makes the function of the whole pair of running shoes affected. You can imagine that if the tire wear of the car is serious or easy to slip, even if there is a better rim and suspension system, the stability of the train will be affected.

Jiangsu Quality Supervision Bureau released the quality analysis report of sampling and risk monitoring for snow boots. According to the new standard of snow boots, the passing rate of snow boots is 75%, but it is worth noting that the qualified rate of snow boots below 100 yuan is only 40%. Experts also warned that most of the snow boots sold at present are not able to defend the melted snow and are not suitable for walking in the snow.

The snow boots were sampled in 60 batches, from production enterprises, physical shops and online stores. The test results showed that there were 45 batches of qualified products, with a pass rate of 75%. The main problems of substandard products were wear resistance, folding resistance, cold proof performance and label marking. The quality supervision department also carried out risk monitoring for water vapor permeability, surface and lining materials. In the risk monitoring, a total of 49 batches reached the target rate, reaching 81.7%.

The sampling results showed that the passing rate of snow boots below 100 yuan was just over 40%, and the passing rate of snow boots between 100 yuan and 200 yuan reached more than 70%, while the passing rate of snow boots between 200 yuan and 300 yuan was 80%, reaching 300 yuan, and the qualified rate of sampling samples was 100%.

In the process of sampling inspection, the quality supervision staff found that the implementation standards of snow boots on the market were rather confusing, especially the standards of snow boots purchased by physical shops and online shops were varied, and the relevant standards of casual shoes, leather shoes, leather sandals, injection shoes and travel shoes were implemented. "The size marking of some snow boots is also not up to standard, some are marked with euro code, others are European code and international common code." Yang Dongfei, Minister of light industry and textile department of Zhenjiang quality inspection center, said many of the three products were flooded with small commodity markets.

It is noteworthy that in this sampling inspection, the pass rate of the three channel samples is actually that the online store has won the leading position with a slight advantage, the pass rate is 77%, the qualified rate of the production enterprise is 76%, and the qualified rate of the physical shop is only 67%.

Is the online shop selling snow boots more reliable? "Reality is not the case," Yang Dongfei explained. The difference in sampling time led to this result. "When sampling last September, only online shops were selling on a large scale, and the shop did not buy many snow boots until the end of October, so there were only 9 batches of samples in the shop." Yang Dongfei said that the next sampling inspection, they will take this factor into account, more scientific and reasonable sampling. He reminded us that online shopping snowball boots should be careful of quality.
