【Set of 2 pairs】 Are your feet feeling tired lately? Are you concerned about flat feet? Recommended for those with these concerns! These insoles support the arch of your foot♪ This page is for size 【L】. Two pairs (for both feet) will be shipped. #aoao shoes S...35-40 (Fits 22.5-25cm) L...40-46 (Fits 25-28cm) The arch of the foot has a function to absorb the impact from the ground when walking or running. In the case of flat feet, this impact cannot be absorbed, which puts a strain on the feet and can cause joint pain, lower back pain, and foot fatigue. These insoles support the arch of the foot with a gentle curve. They reduce the impact on the feet and reduce fatigue and strain♪ They create an arch while also being cushioned, making them easy to walk in! You can cut them to fit the size of your shoes. The arch of the foot tends to collapse due to lack of exercise, age, and long hours of standing. Suitable for commuting, standing work, as well as running, walking, and outdoor activities. *There may be a plastic smell upon opening. It will fade over time. Please understand.
