When doing leg standing, your toes are outward and your heels are close together. This action can help you stretch the hamstring muscle and knee position, thus correcting calf valgus.

Sometimes calf valgus is caused by knee joint internal buckle. If you often feel slight pain on the inside of your knee, it means that your knee is not in the right position. You can improve the position of your knee joint by squatting with your feet.
