Hello, winter is a good season for foot health. I suggest changing a pair of better insoles to improve the environment of shoes. When your feet are warm, your heart is warm. Because you are sweaty feet, putting medicine on the insole can't change the environment in your shoes. It is best to choose a dry, breathable and thick insole. It is recommended to use plant fiber insoles.

Chinese medicine believes that the human body has four roots, namely, ear root, nose root, breast root and foot root. Four are the roots of feet. According to the meridian theory, foot is the beginning of yang meridian and the collateral of yang meridian. "People get old when they are old, and the roots of trees are exhausted first", "Cold starts from the feet" and "Yongquan is where the vitality of the human body lies" all illustrate the important position and role of feet in the human body.

The flow of blood can also make the body feel warm. The foot is the organ farthest from the heart and has less blood supply. Feet are also places where the fat layer is thin in body organs. When the foot is attacked by cold evil, there will be chills, which will affect the flow of blood and lead to cold in the body.

I hope I can help you.
