I often see the opinion that carbon plate mounted shoes only work at high speeds, but I try to understand the reason.
For example, the running economy is completely different between the “fast” runner at 5:00 min/km (10 km about 50 minutes) and the fast runner at 3:30 min/km (10 km about 35 minutes).
From my own training experience, running at 3: 30/km is almost a sprint sensation - especially during stride practice - I feel that I have a much greater strength on the ground every step. On the other hand, faster runners can run much more efficiently at 3: 30/km.
There was a question:
・ When I run at 3: 30/km, do I use more carbon plates than runners at the same pace?
・ If you make the same effort (relative effort) as a fast runner, can you benefit from the same level?
・ Finally, because heavy runners add greater power every step, can running at a slower pace benefit greater?
Slow runners have certain advantages, but at low speeds the difference from conventional shoes shrinks. The biggest question is whether carbon plate shoes are about $100 higher than conventional shoes, but not less than 1% advantage
Although the NVF2 is effective in running economy even at 12 km/h (marathon pace of about 3 hours and 30 minutes), in the high-speed range of 14 to 18 km/h, the effect may be reduced (1.4%) compared to conventional studies (2.7 to 4.2%). At 10 km/h (marathon pace of about 4 hours and 20 minutes), this effect may be further reduced (0.9%).
It’s more than $100.
Running shoes You can run 300-400 miles with one foot.
Alpha fly tread wear is very noticeable when running 50 miles. After that, there will be a negative effect on performance.
I don’t know the science of running (shoes, nutrition, etc.), but even if it is a placebo effect, I wear carbon shoes in the race. It doesn’t matter if it’s actually getting faster. Feel fast.
100 percent. I’m a slow runner but I do feel different when I put on my carbon plated shoes.
When you answer a question, from the conclusion, it is a case-by-case.
Shoes contribute to improving efficiency. Many people interpret efficiency as speed, but it actually means that the cost of maintaining the pace of 3:30 minutes/km is reduced. It is not always possible to run in 3:28 minutes/km.
I can’t affirm. The effect depends on the individual and the shoe. Some of these shoes have poor performance.
In terms of efficiency, there is probably no effect. However, if you disperse the number of steps in the marathon distance, the effect will appear.
In the latest findings, the effect or absence is mainly dependent on biomechanics (stride and front foot landing). In addition, it is also important to convey the power to the body. Weight is not an element of success, but heavy/slow runners are likely to be inferior to light/fast runners.
Certainly, I think the most affected is biomechanics. At least in Nike Alpha Fly 1 and 2, the height of the stack height and the change of the form change my stride. Sometimes there is a spasm in the femoral quadriceps during the marathon, which is not seen in the shoes you usually wear.
It also depends on the strength of muscles and tendons that can respond to changes in walking. In my case, plantar fasciitis and the whole foot are adversely affected, but after careful training with a soft nylon plate (e.g., Sockney Speed 2), running a race with carbon plate shoes does not feel pain. The speed does not increase, but you can maintain the pace even at the end of the race. What I realize most is that fatigue caused by shock is greatly reduced.
Even mundane runners like me (at most!) realized that using plate shoes can gain an advantage in racing. When I bought a plate shoe for a race (mainly a half marathon) that runs in the year, it seems that it is actually running faster than usual training shoes.
The half marathon often runs at an average pace of 5 minutes 10 seconds to 5 minutes 15 seconds/km, but you can feel the effect of plate shoes in this speed range.
Carbon plates provide greater repulsion and faster reversal speeds, so the faster you run, the more you benefit from slower-paced people.
The relative amount of effort is not important, and it is necessary to load plates and forms more aggressively to get more effect.
What is the weight increase? Research in this field has not progressed much, but to guess “no.” This is because, while adding greater power, moving larger masses requires greater repulsion.
it’s an interesting question.
I’ve written before, but I’m an adaptive runner. In other words, one ankle is fixed due to a former injury. I was aiming to qualify for the Boston Marathon for adaptive athletes (6 hours limit). In the first challenge, it was less than 4 minutes and qualified in 5 hours 56 minutes. During training for the Boston Games, he obtained an alpha fly in anticipation of some effect. I asked myself, “Is it effective when I am so slow?”
The first time I had a training run with this shoe, the time was reduced by 45 seconds per mile. I couldn’t believe it! After that, I alternated between Fry and my usual training shoes, but the difference was maintained.
The race was over 5 hours 40 minutes before the target time. This was about 45 seconds faster than the previous record.
In other words, it is not necessary to get the effect of this shoe.
Certainly, however, when supplemented, the shape of a particular shoe is designed for faster runners, which can hinder the walking capacity of a person who walks very slowly, for example. This is actually true for any shoe, because some shoes conform to elements such as heel landing and front foot landing, while others interfere.
In terms of comfort, fit, and comfort, there are definitely “just right” effects or “Cinderella effects.” Super shoes contain a lot of soft forms, while also having a very hard carbon plate. Running for more than 4.5 hours or more than 5 hours, super shoes may start to feel very hard and very uncomfortable. Psychological and spiritual benefits, as well as slight performance improvements that may be possible for slow runners, should be balanced with the effects of long runs on such relentless shoes. In addition to a hard and rigid feeling of running, it is often unstable, causing burden on other parts such as feet, ankles and calves. It’s not the best option for everyone.
I am the slowest runner among my friends, and buying expensive shoes is because it is comfortable to wear. I like cushioning. Instead of running for speed, run to enjoy running. And I want to taste it. If your feet are comfortable, you can enjoy them even more.
The feet are soakoney, the face is smiling, the ears are music, the hair does not feel the wind.
The carbon plate mounted shoes are designed for the extremely specific running form of racing. It’s obviously unnatural when walking. It is literally a thick shoe.
I have experience running with Bayperfly and Endorphin Pro 3/4. As a personal impression, I felt the weight of the shoes when running slower than 9 minutes/mile pace, but it was very effective at 8 minutes/mile pace or higher.
I think we should understand output rather than speed. Even at a “slow” pace, this shoe will respond if you apply strength to advance. But if you run lazily, at least I feel that the shoes are heavy and dull.
The less mentioned point is that not all super shoes have the same performance. It is entirely possible to design a super shoe that actually performs better than a runner with faster runners. The composition of the form, the weight of the shoe, the shape of the shoe, and the design and placement of the plate greatly affect its performance.
Remember that the plates on the shoes (whether carbon or not) are not springs. The plates basically stiffen the shoes, resulting in some effects: improve the mechanism of the ankle and ensure that the ankle and calf muscles do not work too much to get the same speed. Due to its rigidity, the heel is usually raised faster. It also contributes to energy savings by accelerating the compression and expansion of midsole forms.
The extent to which these effects are shown has different advantages for each runner. Fortunately, shoe makers are working on product designs with diverse runners. This is the underlying idea of the difference between asics metaspeed edge and sky. This kind of evolution will continue in the future. Even if a manufacturer starts developing models based on the expected completion time, it’s not surprising at all.
