These rain boots are distinguished by an adorable black and white stripe pattern and bowtie adornment. A classic piece in a modern style and made from an environmentally friendly natural rubber. The boots are made of waterproof natural rubber with a cotton lining. This material regulates temperature and is a natural sweat-absorbing material that keeps feet dry. Natural rubber is a plant material and, under certain conditions, insoluble particles could rise to its surface. As with leather, small imperfections are the hallmark of natural materials.
