The world is waiting for a talented runner who will not raise the human marathon to within 2 hours.

The current marathon world record is 2 hours 01 minutes 39 seconds, created by Kenyan Erude Kip Jog. However, this is not his best result. He had ran 2 hours and 25 seconds in the “Break the Challenge” held by Nike before, and in the “159 Challenge” in the previous days, he finally To get what he wanted, he ran out of the sky, 1 hour, 59 minutes and 40 seconds. Of course, these two results were not recognized by the IAAF.

By the way, Erude Kipjog’s running shoes in the game of breaking the world record is Nike’s Vaporfly 4% Flyknit, which is a pair of outstanding legendary running shoes, just pay attention to the major marathon events. You will find that these running shoes are simply explosions on the field. The 4% meaning is that Nike once claimed that these shoes can improve runners’ running efficiency by 4%. Nike’s new ZoomX Vaporfly NEXT% is a step closer, claiming to increase 5% running efficiency.

▲ The pink shoes worn by the escorts around Kipogog are ZoomX Vaporfly NEXT%

But the protagonist we talked about today is not Nike’s two flagship running shoes, but Li Ningfei running shoes that appear as a challenger.

The most intuitive challenge is the price of Feiji 2099 yuan, exactly the same as ZoomX Vaporfly NEXT%. Li Ning’s ambition is evident.

Everything for light and bombing

I used to mention the weight of the Adidas AlphaEdge 4D: 42 yards weight is more than 400 grams, almost the same weight as the mainstream basketball shoes, this weight makes it not suitable for long-distance running, but is suitable for daily walking .

If AlphaEdge 4D is a tank in running shoes, then Li Ning Feidian should be the light cavalry in running shoes: only 177 grams (US9 yards, Eurocode 43)

▲ This new material technology was called “beng (four sound) technology” by Li Ning

The reason for this light weight is that it benefits from the application of new materials. For example, the new material used in flying power is called E-Pebax (a nylon elastomer), and the ETPU material used in Boost technology is similar in many places, such as the appearance of white, the form of “popcorn” polymerization, and the superior elasticity. and many more.

The difference is that the density of E-Pebax material is lower, and the density after foaming is about 0.11-0.14g/cm3, which means that the density of the material in the fly-up midsole is only 1/8 of that of water. about.

▲The amount of E-Pebax material is quite sufficient

So don’t talk about the feeling of the foot after the foot. When you pick up the shoes by hand, you can already feel the lightness.

In fact, in addition to the midsole material, Li Ning is also trying to reduce the weight as much as possible. Compared to the lightweight midsole material, the rubber outsole of many shoes is much denser, but there is also a contradiction here: the outer sole is thin to make the shoes lighter, but not wear-resistant; The thicker sole has become heavier.

▲ Flying electric sole exploded view, the bottomFang is GCU material

Therefore, Li Ning gave up the traditional rubber outsole and used the new GCU technology. This material has a thickness of only 1.5mm on the flying electric running shoes. The amount of use is very restrained, which can greatly reduce the weight of the shoes. . The reason why it can reduce the amount of this material is because it has several times the wear resistance of the traditional rubber sole, and it is suitable for the slip resistance of various road surfaces.

If you rely on these two technologies, the weight of the flying power can be controlled at about 150 grams. The reason why it came to the weight of 177 grams is because of the addition of the full palm carbon plate.

▲The black part is the carbon fiber sheet

As a veteran new material, carbon fiber is used in the automotive industry. The main reason for using carbon fiber sheet in shoes is because of its high strength, toughness and light weight.

As a marathon running shoe, anti-twist and force feedback is especially important. For example, many jogging shoes that do not use carbon plate “or other skeleton structure” may have excessive deformation of the forefoot during running and gait torsion, and this carbon plate running through the whole pair of shoes is equivalent to shoes. The skeleton allows the runner to “stable the waves” during the running.

More critically, as aA kind of tough material, the carbon plate can “apply to others”, and the E-Pebax material with an energy feedback rate of 80% can make the runner feel the “lifting force” during running. “Rebound force.”

Compared with the fabric material with better wrapping, Feidian uses a thinner lightweight material “MONO yarn”, which is more breathable and translucent texture makes the upper more scientific, but the forefoot The package is also reduced accordingly.

As a flagship running shoe, the design of the flying power is basically no match for the fashion wear. The most eye-catching green color is the plastic track, the asphalt road, and the treadmill.

The meaning of running

As a person who does not have the need for marathon (capability), let alone long-distance running. I used to run very rarely. Even if I went to the gym more frequently recently, I did an aerobic exercise. It is said to protect the knees, but to get a deeper look, it is better to compare the Buddha system with the elliptical machine, and the treadmill needs to constantly drive itself to keep up with the rhythm.

Until once, the coach took me down from the elliptical machine with a scornful look. After I got on the treadmill, I began to discover the joy of running, and I began to pay attention to the performance of the running shoes during the running.

In order to promote this running shoe, Li Ning sponsored a lot of marathon runners, and some top runners ran out of these shoes for 2 hours and 10 minutes.

Maybe one day humans will “break the second”, but the individual differences of human beings are too big. Most marathon runners are pursuing “breaking three”, more people who are unable to run marathons, such as me, goals. It is the next time you can stay on the treadmill for a little longer, or faster.

In this time, I stepped on the treadmills on the PureBoost, React, JoyRide and Zoom Pegasus 36 Trails. Of course, I also stepped on the treadmill on the fly. The price of these running shoes ranges from 500 yuan to 2,000 yuan. The cheapest PureBoost is also good for half an hour on a treadmill. The golden choice is not good. React For me, it’s actually a shoe that walks more comfortable than running. It’s soft and soft, but it doesn’t rebound quickly. The first generation JoyRide performed well, fits well, and the soft and hard rebound is also brisk. Integrated terrain running shoes Zoom Pegasus 36 Trail Strictly more suitable for outdoor, on the treadmill performance and React, the soles and uppers are slightly harder.

As for the flying power, I have to admit that as a running shoe with a price higher than two gears, its comprehensive performance is obviously one or two grades stronger than the above-mentioned running shoes.

First of all, I don’t have to mention the light, the upper footAfter that, there is indeed a feeling of “lightness and nothing”, which of course is related to the weak wrapping of MONO yarn fabric.

An additional benefit of MONO yarns is quick drying, which is water permeable but does not absorb water, compared to the water absorption of the fabric. Once I was wearing it to the gym, the rain was soaring, the socks were almost all wet, but after wearing the socks, I was wearing a flying electric barefoot and there was no feeling of stuffiness.

But it’s even more impressive.

Compared with the general running shoes, the flying sole has a tougher sole. This is reflected in the daily movement, its force deformation is limited, and there is no such thing as React or some Boost. Even so, its limited deformation still provides a quick rebound, so there is some lightness in walking everyday.

In the running scene, the force feedback effect of the combination of the midsole material and the carbon plate came out.

When the forefoot touches the ground, because of the presence of carbon plates, the forefoot of the flying electric shoes does not bend as much as other shoes, and the arc is almost the same as the original curvature of the carbon plate. When I try to bend the forefoot At the time, I found it difficult to do because the rigidity of the carbon plate inside is too strong. Even if the carbon plate feels pressure by the weight of the body during running, it will feed back and form a thrust.

In a word, flying power is not a running shoe that makes people happy to run, but the more standard they run, the lighter they feel. Once the action is too large or deformed, it will forcefully “resist”, thus pulling the running position back on track, reducing unnecessary physical exertion.

For marathon runners, the standard running posture and stable pace are especially important. From this point of view, the flying power is a running shoe that allows the runner to form a running rhythm.

For non-professional runners, such as those I run in the gym, it’s also a running shoe that makes the running experience easier.

From the perspective of the shoes themselves, the flying power can indeed win the international brand 1500 yuan or less running shoes, which also gives Li Ning a price of 2099, against the Nike flagship ZoomX Vaporfly NEXT%. However, in the eyes of many people, this is also the location of the slot. ZoomX Vaporfly NEXT% and Vaporfly 4% Flyknit have experienced a lot of occasions. It is a more secure choice for runners in need. Why not choose a price advantage? Flying power without proof of large-scale events?

In the novel and animated work “Strong Wind Blowing” with the theme of long-distance running, ten people with different personalities and talents are gathered together to continuously break through the self-completed “Hakone rumor” long-distance race with a total length of 217 kilometers. Finally ranked the tenth story.

Among the ten people, there are long-distance runners who have suffered injuries, but also have talents but long-running geniuses who leave the track because of impulsiveness. More, they are ordinary people’s long-distance running stories. The first one is absolutely strong. But the tenth is the best result they can get.

As the first product to enter the top running shoe market and compete directly with Nike, the market prospect of Feidian is not good enough, but the symbolic significance of taking the first step is enough.

▲Kip Georg broke the Nike new running shoes

As the legendary runner Kipkog runs, the goal is to “break the second”, while some people are not just for the other than just the last time, Nike sponsored Kip Jogg wearing Nike new shoes Finally, on behalf of humanity, the success of the second, Li Ning also took out the flying power to try to break through.
