To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
My 13-year old got a pair for xmas last year & I just bought her a second, identical pair in a larger size. She loves them -- wears them all the time. They are durable (despite 4x weekly use in winter, they are still in good shape for her younger sisters). She says they do take a little time to mold to her feet -- she wore with a pair of socks for a week, then dropped the socks because she said they were perfect. While they aren't my taste -- she loved them so much that we even got the identical color this time.
I bought these for my wife, who refused to spend the $ on Ugg’s. I have the same pair in black and wear them all winter as slippers. Both my kids boy and girl have them and wear them constantly as shoes. Her main complaint is the rear lip of the shoe. They are comfy but if she walks at any other pace than slow walk her heal pops out of them. She’s usually a 6 and I bought 6.
