Amazon calculates a product’s star ratings based on a machine learned model instead of a raw data average. The model takes into account factors including the age of a rating, whether the ratings are from verified purchasers, and factors that establish reviewer trustworthiness.
Great looking waterproof boots , fantastic value for money . Perfect for walking the dog on wet days. Got half a size bigger to fit bigger socks in but no need , stuck to your win size as their quite generous .
