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.
When I received these boots I was over the moon and gave 5stars...... After wearing these boots I'm disgusted and would give NO STARS!!!!!!!! There rubish, both boots have split in the same place..... Its not like I'm climbing mountains with them I'm out walking my dogs in the woods. DONT BUY THEM!!!!!!!!!!!
