First Use: Simply slip them on! Ensure you have appropriate socks for comfort and to manage moisture, as rubber wellies typically offer limited breathability. Sizing: Regatta Amelia Wellies are available in standard UK adult women's sizes. It's generally recommended to choose your usual shoe size. If you plan to wear thick socks, you might consider sizing up by half a size, though this product is typically available in full and half sizes. Care and Maintenance: 1. Cleaning: After use, especially in mud, rinse the wellies with clean water to remove dirt. Use a soft brush or cloth for stubborn mud. 2. Drying: Allow them to air dry naturally, away from direct heat sources like radiators or direct sunlight, as extreme heat can cause the rubber to crack over time. 3. Storage: Store them upright in a cool, dry place. Avoid folding or creasing the rubber to maintain its integrity. 4. Protection: Periodically, you can apply a rubber conditioner spray to help maintain the flexibility and extend the life of the rubber.
