We recommend keeping your Mastra Ma’ shoes inside the provided dust-bags and box, out of contact with alcohol, oils, solvents and water. In order to maintain the shape of your shoes, you may fill them with tissue paper or use a shoe tree. Cleaning and polishing. Please do not use any detergent. You may instead wipe your shoes with a dry cloth or, where appropriate, use leather care products in a neutral colour. Please follow the instruction carefully and spot test the selected product in an inconspicuous area before use. The lining is made from smooth goatskin. You can gently remove impurities by using a clean damp cloth. General recommendations. The soles are made from cuoio leather injected with rubber. Marking upon first use is part of the normal wear and tear process of the shoes and it is not a manufacturing defect. We do not recommend walking on water or under the rain with your Mastra Ma’ shoes, as this may alter both the soles and the uppers made of soft calf leather. It is normal for the heel tips to deteriorate with extensive use. We do recommend changing the tips once they start to wear down and before the inner heels get damaged.
