Explanation
In the Netherlands, showing the soles of your feet is considered impolite in social settings, as it is seen as a sign of disrespect or carelessness. This stems from broader Western norms where feet are considered dirty and pointing them at others is rude. While not as severe as in some Middle Eastern or Asian cultures, it is still best avoided in polite company.
Local Tip
Keep your feet flat on the floor or crossed at the ankles, and never rest your feet on furniture or point them toward someone.
