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.
It's an attractive boot and I like the pull-on tab. It has a grip bottom. I have a strong leg so the top of the boot scrunches down a bit because the top isn't wide enough to accommodate my leg and I can't put my pant leg into it. I ordered a 1/2 size larger and I'm glad I did.
