sports shoe guru: how to choose the best running shoe - what's the best air purifier to buy

Frank SwainCheap sneakers can be as good as expensive sneakers, says Beno Niger, a sports scientist who helped design David Beckham's new book on sports shoe bioengineering, you say expensive running shoes are more protective than cheap shoes.
Isn't that evil?
This is a bit exaggerated.
But, despite all the developments in the sneaker design, the relative frequency of running damage does not seem to change much in the last 30 years.
The literature shows that shoes are a secondary role in the development of injuries.
If you bring a group of people and want to hurt them, 20-a day-kilometre run.
Many of them will be injured in three weeks.
Distance running, strength and recovery time are the main factors.
So what should people pay attention to when buying a new pair of sneakers?
The problem is that if you go to the store and want to find your best shoes from a bioengineering perspective, you don't know what to do.
Sometimes things you do, such as video analytics that spin your back foot, may not help.
The only way to assess if a shoe is right for you is how it feels.
If you feel comfortable in your shoes, it may be good for you.
We did a study with the soldiers, where we gave them six different plugins that they chose their favorite.
Within four months, 53 fewer people were injured with inserts than those without them.
The ad shows that a more expensive shoe will make me run faster or jump higher?
Expensive shoes can be used as training equipment to activate some muscles for most users.
Or it can use materials that last longer.
For regular runners, however, it is difficult to distinguish between actual functional design and gimmicks.
In general, the more the shoe controls movement, the more it's like an actor, which means you have some muscles that don't work anymore.
This may mean that you lose some muscle strength and are more vulnerable to injury.
You helped develop unstable Masai MBT shoes.
Is this design really working?
Yes, about people.
The main benefit is to train small muscles that go through the ankle joint and reduce pain in the knee and lower back.
However, some claims about these unstable shoes are exaggerated, such as the general muscle tone they claim to produce.
Some people say we can do it without shoes.
What do you think of running barefoot?
It is claimed that there are fewer injuries when you run barefoot, but none of them are confirmed.
If you look at the performance, most newspapers think the advantage of 3 to 4.
With a few exceptions-Abebe Bikila in 1960 and Zola Budd in their 1980 s-people don't run barefoot, so it may not be an advantage, or we just don't get used to it.
In the future sports shoes, what kind of technology will we see?
I think sooner or later there will be a shoe that tells you "you should change the training a little, you run for injury"-a "smart shoe" that tells you how to train ".
