For the public, shoes are used to protect the feet, but if you ask the major sports shoe brands, everything from foam soles, elastic uppers, laceless sneakers to toe socks will change your steps. Walking, running, and everything in between. For Nike, it still has sneakers commonly used in basketball and other sports, but as far as running is concerned, the fabric upper that defines the Flyknit series is still a sportswear brand, even the latest Nike React such as Nike Infinity Run Flyknit. Comes with powerful exercise effects. 2Enhance running performance. Nike Mercurial Vapor Nike tends to emphasize aesthetics while providing runners with low-to-medium mileage shoes. We believe that Nike React Infinity Run Flyknit 2 is just like that. In true Nike fashion, this pair of shoes does not look like typical running shoes, because its curved midsole and smooth upper make the sneakers used as both sports shoes and casual shoes. In the store, the shoes are available in four colors, four for women and seven for men, or you can choose NikeID to create your own color scheme to bring more eye-catching beauty. For users who are not familiar with NikeID, this is Nike’s free customization service, and shoppers can design these new shoes by themselves.

Shoelaces and tongues firmly fix the feet on the shoes, and add locking threads and half-sewn tongues to ensure that the shoes will not slip during running. But be careful, some people complain that your tongue is fragile, so be careful or your tongue will eventually be torn. The upper has been completely redesigned from the predecessor using Flywire and Flyknit technology to ensure support and breathability. Nike Mercurial Vapor Flyknit technology uses different weaving methods of lightweight and strong yarns. This fabric forms a one-piece upper that not only supports the foot, but also secures the foot in the shoe. It can do all of this while still being stretchable and breathable, providing the best comfort for any athlete. The addition of Flywire technology adds Vectran filaments to the shoes to increase support and flexibility. The NASA-inspired material is lightweight, but by wrapping Vectran strands around the shoe, it can effectively form a locked fit. The material may be thin, but it is undoubtedly durable. The cushion around the ankle is comfortable and soft, and does not cause blisters. It also greatly reduces strain on the ankle, allowing runners to redouble their efforts. The first version of the shoe was designed to reduce injuries to runners. Therefore, one of Nike's first tasks is to ensure that the ankle is protected during running, so they decided to keep the heel clip of the shoe. The clip is made of a hard plastic called TPU, which creates a stronger heel, which provides extra stability at the ankle. For Nike, it is best not to remove the pull tab on the back of the shoe. This is a good move, because without it, the shoes will be difficult to remove and put on. When it comes to shoe soles, the hardest part of Nike is Nike's React technology. The insole is made very thin, especially to make the flow channel closer to the React foam, so as to obtain a more sensitive feeling. The midsole is very sensual in thickness and width. The 9mm sole provides comfort, while the thickness provides good stability and support. The midsole also has good arch support, making the shoes more comfortable. Nike is known for creating slim feet. As mentioned earlier, the toe box is very suitable, and the arched support of the midsole makes the contours of your feet more visible. This is beneficial for regular runners because it can effectively distribute body weight. However, this is bad news for people with flat feet. These shoes will make you very uncomfortable. You can solve this problem by adjusting the size, but some parts may not fit, some parts feel tight, and others feel loose. The sole has both a flared heel and toes. This curved sole makes the transition from the runner's heel to the toe easier, and has a slight swing. It can also provide greater strides when running without harming the thighs, knees and calves. This function is very useful for controlling our motivation and can further push us forward. The shortcoming of this pair of shoes is lack of elasticity, because Nike hopes to make the impossible become a reality when making shoes that are both soft and durable. Our steps are limited, and it feels denser than running on the cloud. However, this experience may vary from runner to runner. We appreciate the compactness of the React foam and its energy feedback, but in terms of plush, Nike React Infinity Run Flyknit 2 disappeared. The outsole of the shoe has two different parts. The upper part is fixed linin
