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.
These are very good short wellies much better than my previous three pairs and seem much stronger and better quality and fit than most I have tried recently including well known make. Would recommend them.
I give my first pair to my husband as they were too big, my second pair fit, but the left foot is slightly bigger than the right. They are both stamped as a size 5, I just wear thick socks. Great for walking my dog.
