To ensure the longevity and authenticity of vintage leather shoes, they should be regularly brushed with a soft brush to remove dirt and, if necessary, cleaned with a slightly damp cloth. Traditional leather care products such as leather grease, oils, or beeswax are particularly suitable, as they keep the material supple and form a natural protective layer against moisture. After cleaning, the shoes should always be air-dried and never exposed to direct heat to prevent the leather from becoming brittle.
