This basically means that TPU shin helps to guide the power of the foot to move to the "jumping device" of the forefoot, which in turn provides more energy returns, theoretically, increasing the verticality. As for how the device works, APL is silent about the details due to the process of obtaining the patent. As for how shoes feel when using this equipment, it is subtle, but it is obvious. It doesn't provide the best stadium feeling ever, but it is surprisingly decent for the number of "things" in the midsole. The feeling of the midfoot shin is actually very familiar with any shoe with a solid shin-you can feel it bend under pressure and almost "bounce back" when you pass through it. As for the feel of the forefoot device, it's a bit difficult to explain. It must be firm, but it is also very sensitive. The harder you push, the more you feel it is giving back. I can really feel some extra elasticity in my jump, which is not only the evidence that I feel that my suspension time has increased, but also the height I can reach. Always. (In popular translation, APL Concept 1 is called "plug-in" equipment, which completely depends on the "propulsion device" placed in the midsole. This artifact is distributed in the forefoot, the ball of the foot (the bone behind the big toe) and the plantar extension belt (people who don't know the truth can consult a physiotherapist and a doctor, or get a foot massage to know what I'm talking about). In addition, the outsole is & high density thermoplastic polyurethane. Ejection? "The handle (all high-tech) can further improve the performance of compression-propulsion-lift-off. Pushing the handle can improve the stability of the forefoot and ankle to a greater extent, and at the same time absorb the impact force on the foot during exercise and transfer the impact force to the "filling" part. Ejection? "System, improve the vertical takeoff height. )
If the complicated Martian technical terms in the previous paragraph are translated into vernacular that adults can understand, the general idea is that the "increasing bounce device" located in the front palm provides users with a lot of feedback force through the elastic deformation of TPU, thus achieving the effect of increasing bounce. As for the details of how to increase the bounce, APL company conservatively chose not to talk about it because of trade secrets and patent applications. When you put your foot into the target shoe during the evaluation, you will feel a subtle difference and an unprecedented sense of energy feedback. Maybe this shoe can't give you the best sense of venue, but considering that the midsole is made of such complicated technology and various materials, APL Concept 1 can definitely bring you a little surprise. In fact, the cushioning effect of the midsole is similar to that of other non-air-cushioned midsole (such as Adi adiprene⊕). When the sole exerts force, it can immediately feel strong elasticity. As for the feeling of the core technology of increasing bounce in the forefoot, it feels a little, but it can't be explained in words. In short, it is not slow or solid, and the feedback is excellent. The harder you work, the more you can feel the rebound provided by shoes. To be sure, I really think I can jump higher. Apl concept 1 not only provided me with significantly longer battery life, but also confirmed my feeling of jumping higher from the results of many touch height tests.
It may not be the most scientific and accurate method to measure the degree of bounce increase by touching the height test, but it is definitely the most practical. Whether you can block shots at will on the court does not depend on how high your feet are from the ground, but on the height that your hands can reach after taking off. According to my personal test, after wearing APL Concept 1, the height of each jump can be increased by one or two inches (1 inch =2.54 cm). In order to get more rigorous and objective results, the comparative evaluation of several different baskets was tested by changing multiple pairs of shoes. Amazingly, I get consistent results every time, so the only conclusion I can draw from these test results is that, yes, APL Concept 1 can improve the bounce.
In addition to increasing vertical bounce, APL also claims that Concept 1 can relieve leg fatigue. Indeed, a sneaker that can provide such powerful energy feedback really needs to keep your legs relaxed during exercise. It's difficult to draw a conclusion only by touching the objective data such as the height of backboard, and the measure of relieving leg fatigue is subjective. Because I didn't wear shoes in actual combat, I can't confirm or deny the effect of relieving fatigue claimed by APL, but the function doesn't seem obvious through trial jump. Because a large number of technologies and materials are located in the midsole, the back palm of sports shoes is slightly heavier. Another possible reason is that due to the poor air permeability of sneakers, there will be the illusion that sneakers are heavier after sweating.
