Nike running shoes is best shoes in summer

Summer is a good time to doing sports. Running in the morning before work is a very good way to relax your body and make you vigorous. Listening to music is a good way to stimulate cells. However, without a good running shoes, it is hard to effect your body.

There are various of running shoes in market. However, it is hard to find the best one for you in summer, why not try Nike? Nike running shoes is best shoes in summer.

Nike shoes designed based on human foot. The arch of the foot is formed by the tarsal and metatarsal bones and strengthened by ligaments and tendons. It allows the foot to support the weight of the body in the erect posture with the least weight. The height of the arch determines pronation and foot type.The arch height of the foot can easily be checked using the wet feet test. People with a Low arch do not have a distinct curve along the inside of the foot. The imprint taken in a wet test may show nearly the entire foot. People with low arches are more likely to overpronate which can result in injuries. Insufficiently expressed arches are called low or fallen arches. The term flat feet applies to the arch which is sitting on the ground completely.

Over the last 20 years or so, all the major running footwear producers developed specific technologies aimed at helping runners with flat feet run in comfort and safety.
The key words you have to remember are: stability, support and motion control. If Pegasus is Nike's trademark for cushioning, the Structure Triax is their trademark for stability running shoes, here in its 12th edition. As many other running Nikes, it comes in two different gender-specific versions.

The midsole post is the injection of harder foam (recognizable by the darker grey colour) right underneath the foot arch. The reason why the post is so important is that the harder foam, just in the place where you need it, supports your arch from collapsing too much during the strike on the ground if you tend to overpronate. The dual density post in the Structure Triax 12 is very interesting in the fact that it is not a solid block of a harder foam, but it is "broken" by inserts of normal density foam in order to allow flexibility. The second great news here is that these inserts are different in the mens and womens version of the shoe, the latter being engineered to give extra flexibility – as womens body mass is generally lower than mens: womens don't put so much pressure on the shoes' midsole and need an extra help in order to properly flex the midsole during the running gait.

The midsole post is completed and aided by the addition of a midfoot plastic shank, that Nike calls Footbridge. As we've seen in many other shoes, the Footbridge is a key component in the stability of a shoe as it "keeps your gait together", preventing you from hitting the ground with your heel and then transitioning to your toes at two very different (and dangerous) angles. The shank of the Structure Triax is asymmetrical and is not the most robust of the category – but it performs a fine job and it adapts to the shoe's philosophy of being supportive but flexible.

Sole units' technology are completed by Nike Zoom Air (Nike world famous cushioning technology, the Zoom version offers the same shock absorption capabilities of the Air and Air Max but in a much thinner unit) in the heel and forefoot together with a decoupled crash pad on the heel. The purpose of the crash pad is to give the maximum support on the area of maximum impact when the heel lands on the floor and then propagating the force to the rest of the heel where the Zoom Air unit provides the appropriate cushioning.

It is very comfortable in wearing of Nike running shoes. Even Nike company produced many different types of Nike shoes, like Nike Air, Nike Dunk and so on. Nike is not satisfied with these achievement. Nike promises to improve their technology of innovation.
