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
