I love Havianas, but buying them online is frustrating. I bought a pair for each of my kids, and I had to send them back and order two sizes up. Where it says US toddler 8, I suggest to add two to order the correct size. So for my toddler who wears an 8, I bought a US toddler size 10, and for the other who wears a big kid size 2, I ordered a 4. But other than that, the flip flops are always perfect: very comfortable with no blisters after wearing them for the first time. And durable. Love these shoes, great prices on Amazon, but have to be careful with the sizes as they run small.Great product and fast shipping!
