Maintenance and Care
Proper care will extend the life and maintain the performance of your ECCO golf shoes.
- Cleaning:
- After each use, wipe off dirt and debris with a soft, damp cloth.
- For stubborn dirt, use a mild soap solution and a soft brush. Avoid harsh chemicals.
- Clean the outsole regularly to maintain traction.
- Drying:
- Allow shoes to air dry naturally at room temperature.
- Do not expose to direct heat sources (e.g., radiators, hairdryers) as this can damage the leather and waterproof membrane.
- Stuffing with newspaper can help absorb moisture and maintain shoe shape.
- Leather Care:
- Regularly treat the leather with a suitable leather conditioner or cream to keep it supple and prevent cracking.
- For enhanced water resistance, apply a waterproof spray designed for leather footwear.
- Storage: Store shoes in a cool, dry place away from direct sunlight.
