Amazon calculates a product’s star ratings using a machine learned model instead of a raw data average. The machine learned model takes into account factors including: the age of a review, helpfulness votes by customers and whether the reviews are from verified purchases.
I had this reebok princess before. This is my third pair of shoes because I love it so much. Comfy shoes but because of my foot problem will probably need extra insole. The size fit as expected since I had the shoes before but I recommend you to try it at shop first. My feet usually fit size 37(6-6.5 usa) shoes but on this one I have to get size 38(7.5 usa).
