these are by far the most comfortable flip flops I've ever used. I have some Rainbows and Reefs that I used in college, but the Havaianas are somehow just more flexible and make your feet lighter.
I wear size 8.5-9 and the 39/40 Brazil is perfect! And I mean perfect because my heel fits right before the edge of the sandal and I love it! The strap is a tad bit shinier than the rest of the flip-flop but it's fine with me!
Great fitting beach flip flops and anywhere to go and wear in warm weather. Look great Would highly recommended them
