The heat coming from the streets is a warm feeling that brings cool feeling vests and shorts.

When the heat is reduced, experts warn that the flip flops will suffer from both feet, with flat feet, sciatica and even bone spurs.

Because of the inherent defects in the design of the flip flops, the flat and thin bottom can not provide enough supporting force, and the huge reverse force formed on the ground is springback to the feet, causing the foot to be easily damaged and injured, so the public can not wear a flip flop for more than one hour at a time, especially to avoid the high speed flip flops that will cause injuries.

When walking on both legs, the whole body's gravity will spread to the ground through feet, and then rebound to the feet. The strength of the earthquake is equal to three to four times the weight.

Chiropractor and physiotherapist He Yinghui pointed out that the arches of the feet are radially curved as natural shock absorbers. However, the design of flip flops and soles on the market is mostly flat and can not fit into the foot shape, so that the arch of the foot is not adequately supported, which can not effectively remove the reverse force, causing the foot load to increase, which can lead to the loss and softening of the ligaments and tendons, and also make the feet and knees easy to strain, and affect the arch of the arch to cause flat feet.

Obese children and children have worse sequela.

He Yinghui said, the heavier the body, the greater the anti seismic force, the greater the pressure on the feet. If you wear a flip flop without a supporting force, it will be more vulnerable than ordinary people to injury and flat feet. As young children are not fully developed because their feet are not fully developed, they often wear flip flops without protection and support, which will lead to bad walking posture and habits, and the development of their feet may also be affected.

On the other hand, the flip flops will also make the toes suffer, because the wearer will unconsciously grasp the upper with his toes when walking. The long term flexion of the toes will cause strain and nervous inflammation.

The flip flops can also cause the plantar fasciitis to be pushed back when they walk, increasing the pressure on the sole of the foot.

He Yinghui warned that a lot of people are tired of even tired feet, so that their feet continue to suffer from stress and discomfort. As a result, they accelerate the degeneration of cartilage tissue in the ankle and knee, resulting in bone hyperplasia and bone spurs. If the ground's reverse force is pmitted to the waist due to foot problems, it can lead to sciatica with "long tail".

Therefore, he suggested that the public should avoid wearing flip flops. Even if they were dressed, they should be careful in choosing styles, such as choosing shoes with a foot arch and a height of about one inch, and not wearing for more than one hour at a time. If there is any discomfort or strain on the feet, they should seek treatment as soon as possible so as not to worsen the problem.
