When it comes to caring for your Chelsea rain boots with a sponge sole, it's important to remember a few key tips. To keep them looking their best, be sure to clean them regularly with a damp cloth and mild soap. Avoid using harsh chemicals or abrasives, as this can damage the waterproofing and finish of the boots. To help maintain their shape and structure, store them in a cool, dry place away from direct sunlight when not in use.
