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 totally in love this boots! I am a size 4 so I ordered a 5 as suggested by other reviews and fit perfect. So comfy and light. The side is shiny but they do not look cheap. I so recommend this boots.
