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.
I am at the top end of one size and the bottom of the next. I ordered the larger size and it fits perfectly. I especially like the fact that it is long enough to go over my heels and so will protect my ankles and heel from jelly fish! My trip got cancelled so I haven't used it yet but really like it so far.
