The number of bones in the feet of ordinary people accounts for 1/4 of the total skeleton of the body. Most of the bones of the feet are very small and delicate.

Usually, only walking and running with bare feet can strengthen every bone in the foot, but this is obviously impossible for people living in the city.

If you can have a pair of running shoes that are barefoot and protect your feet at the same time, I believe that this will be the most fashionable new product of city men and women this summer.

In 2010, Nike Free series's latest upgrade shoes - Nike Free Run+, explained excellent seismic performance, improved fit and barefoot natural movement feeling.

Wearing such running shoes can not only create a healthy walking environment for your feet, but also restore your feet to the most primitive activity in the fastest time.

At the same time, this is also the first Nike Free sneaker with Nike+ function, allowing runners to know their running distance, speed, time and burning calories in real time, and experience the old walking pleasure through new technology.

Since the birth of Nike Free sneakers four years ago, every design change has been subtle, but it has greatly improved the performance of sports shoes.

In the process of continuous improvement of Nike Free, the outsole structure, which keeps the footsteps in a natural movement, has been widely used in basketball shoes, training shoes, tennis shoes and traditional running shoes.
