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.
I am very happy with these boots, I ve had them for a week now and they are comfortable, provide good support and I didnt need to break them in. I found them on sale so a good deal as well! They are regular/narrow fit.
