MelFlex® is Melissa’s signature flexible PVC-based jelly material, designed to feel soft, durable, and lightweight. |

| Cleaning + wear tips |
Melissa shoes are highly durable and low-maintenance due to their unique MelFlex® PVC material. They are waterproof, scratch-resistant, and do not deform over time. |
|---|---|
| Wear tips |
Melissa shoes should feel comfortable from the first wear, as the material does not stretch, but MelFlex® softens with body heat to gently mold to your foot; socks can help prevent blisters during the first few wears. |
| Cleaning tips |
To keep your shoes looking and smelling their best, wipe with mild soap and a damp cloth, gently scrub stubborn dirt with a soft toothbrush, use a Magic Eraser only on white or light-colored styles, and always air-dry in the shade away from heat, direct sun, car trunks, and washing machines. |
