CASCAIS. This women's rain boot is made of neoprene-effect fabric and monochromatic rubber. It is a reinvention of the classic Chelsea boot in a waterproof version. It has a platform sole with a wavy design and a height of 5 cm. The base of the sole is made of non-slip rubber. The inner insole is lined with fabric for added comfort. It features a side zipper for easy on and off. This model fits true to size; we recommend choosing the smaller size if you are between sizes.
