Deadening the Impact Force

No matter barefoot runners land on forefoot or the middle of the soles of the foot, they can almost avoid the injures caused by the impact force while runners who wear running shoes land on heels causing more impact force than barefoot runners.
The passage also analyzed that now there are many people who believe that barefoot running will lead to injures in feet. But in fact, anybody can do barefoot running on the hardest ground in the world and they do not feel painful at all. What they need to do is just to avoid the skins in feet scratched by hard objects on the ground.
The professor and his research team which is constituted by Harvard University, the University of Glasgow and MOI University from Kenya made a research and comparison on barefoot running and running with sports shoes on during a long period. Barefoot runners can benefit more flexibility and more efficient in feet and calf muscles from running with no shoes on in this research.
Human beings have already been doing running for thousands of years while running shoes only started to enjoy a great popularity in the 70s of last century and if only your heels come to the land when you do running, your feet muscles and calf muscles can exercise nothing. This is the advice that the professor wanted us to notice.
Is it really good for us to run with no shoes on? Todd Byers was only one participant who did barefoot running during the San Francisco marathon race. And there are twenty thousands of runners participated in this marathon race and all the participants wore shorts and T-shirts. In fact, he had done barefoot running in seventy-five times marathon race.
The recent study showed that even the modern running shoes have various hi-technology functions but they did nothing to improve the running scores or prevent injures. People can get benefits from wearing shoes as thin as feet sack or just with no shoes on when they do running. It is a popular view held by some runners. However many medical experts are against this view and there formed a violent argument that one is for barefoot running held by barefoot runners and researches and another is against held by shoes makers and sports scientific institutions. Eighteen-billion running-shoes marketing maybe shook by this conclusion.
Businessmen of shoes-making spoke plausibly to defend their products. At the same time they also held the view that it is helpful for runners to run with running shoes because shoes can prevent feet from tense and twist injures. The new top-grade running shoes designed by Asics have already sold on the market. And this pair of shoes cost 320 dollars and the reason lied in that a device can avoid shakes and deaden the impact force equipped within this pair of shoes. While Adidas also put is new top-grade running shoes into market and this pair of shoes cost 540 dollars. The company named this pair of shoes Porsche fashionable elastic running shoes and its inspiration came from the suspension system of cars and used metal springs in this pair of shoes.
