Japan Has Developed New Running Shoes For Beijing Conditions.

On the 16 day, Alex has made the first haircut for the 5 runners who are defending the women's marathon in Beijing Olympic Games.

According to a report published by the 17 edition of Sankei Shimbun, this is a running shoe that Japanese manufacturers have developed and adapted to Beijing conditions for the marathon runner who is expected to win the championship.

These shoes are lighter in weight and prevent the yellow sand and dust from entering the shoe inside China. This is also the secret weapon for women marathon athletes who are most likely to achieve the goal of winning 2 medals (including 1 gold medals) in Japanese track and field circles.

The race line in Beijing has only a few ups and downs, and the rest is relatively smooth.

In addition to the rapid change of the width of the road, the uneven stiffness of the road also increases the burden on the feet.

Therefore, the soles of the past 3 layers of structure, though convenient for the players to play the speed, will cause a burden on the feet under the road conditions in Beijing.

In order to reduce fatigue, the newly launched running shoes specially adopted the latest development of the "lightweight elastic big" 2 layer sponge material.

Besides, in order to improve the stability of the floor, the thickness of the sole is controlled between 2 and 3 millimeters.

In order to prevent the entry of fine particles such as air pollutants and dust, woven mesh material with small mesh is also used in the upper part.

According to the developers, because the mesh is tightly knitted, "air permeability may not be as good as that of Athens Olympic Games, but because it uses more sweaty and dry materials than before, it is more soft and comfortable to wear."

The weight of one shoe is reduced by 13 grams, which can help her save 5% of her calorie consumption in the 42.195 kilometer race.

In order to defend the defending champion, she assured her staff that the foot shape and left and right center of gravity were tested in early July, and that the new shoes will keep her feet the best so far.

Besides Tosa Reiko, Nakamura Yurika and Misaki Sato Atsuno, and kazaki Kawasaki, the new running shoes will also be available.
