In South Korea, showing the soles of your feet is considered deeply insulting because the foot is viewed as the lowest and dirtiest part of the body. This gesture, especially when directed at someone older or of higher status, implies contempt and is a serious breach of social etiquette.
Local Tip
Always sit with your feet flat on the floor or tucked under you, and avoid pointing your feet at anyone, especially elders or authority figures.
