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 already owned these thongs and have always been happy with Ipanema brand. I like the moulded footbed, I don't get painlike I do with Havaianas. I lost one thong so I was buying another pair. The sizing runs slightly small. I usually take a size 8US/39 EUR in other shoes but I knew my size in these shoes is one up - 9US/40EUR. So size up if you are between sizes.
