Clean and waterproof your suede sandals regularly, (suede spray is very easy to apply) and use a suede brush before wearing so that they look their best. If they get wet, let them dry naturally.
Always use a cream or paste polish on leather sandals-liquid polish can be drying.
Avoid using chemicals to clean exotics skins. Python becomes soft with use, so no conditioner is required.
Use a silicone- based cleaner to polish patent leather, and use a mild soap to remove any haze.
Clean cloth sandals with a mix of detergent and water or baby wipers, and allow them to air dry.
Shoe bags for travel are a must! They will keep sandals from rubbing against each other.
