What color sandals and slippers are the healthiest to buy in summer?

It doesn't matter what color it is. Flat heels are the best. Don't wear sandals for a long time in summer, especially sandals, especially when traveling, playing and activities. In addition, try not to wear sandals, especially when the light is not good and the road conditions are not good. Traditional Chinese medicine attaches great importance to foot health care, and believes that the foot is connected with all organs of the whole body, and ensuring the smooth blood flow of the foot is an effective guarantee for good health. Ten of the eight most important the twelve meridians and odd meridians in the human body start and end at the foot, and many meridians and acupoints of the whole body are gathered at the foot, which is the place where the viscera, meridians and qi and blood perfusion gather. The pathological changes of zang-fu organs can often be reflected to the foot through meridians, so the foot is called "the second heart of human beings".
