Massage insoles are a kind of insole with health care functions. Usually, various protrusions, particles or massage elements are designed on the insole. Its functions are mainly reflected in the following aspects:

- The protrusions or massage particles on the massage insoles will exert a certain pressure stimulus on the blood vessels in the sole of the foot when walking or standing, which will cause the blood vessels to dilate and make the blood flow more smoothly, thus improving the blood circulation in the feet.
- Traditional Chinese medicine believes that the soles of the human feet are a concentrated area of many acupoints, which are closely related to various internal organs of the body. By stimulating specific acupoints on the soles of the feet, such as Yongquan acupoint and Zusanli acupoint, the massage insoles can regulate the body's functions, dredge the meridians and balance yin and yang.
- During walking or standing, the massage insoles can massage and relax the muscles and ligaments in the soles of the feet, reducing the pressure and tension generated in the foot muscles due to bearing the body weight for a long time, allowing the foot muscles to get fully relaxed and rested.
- Good blood circulation helps to maintain the moisture of the foot skin, reduce the occurrence of problems such as dryness and peeling, and at the same time, can also reduce the risk of foot infections such as fungal skin diseases.

These insoles are designed for daily foot comfort and massage, not for medical treatment. Consult a professional for serious foot conditions.
