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.
If Indian/UK size is 5, choose W7, if Indian size is 4, choose W6 and so on (My UK size as per normal standards is 6 which is W8 in Croc. It was too large in size). I purchased based on UK size and had to return as the size was large and then buy again. I returned 2 slippers due to size confusions and finally got the right sized one.
