These flip-flops are super in quality but i was disappointed with the size i order. I received a pair of these Havaianas Brasil flip-flops in pink as a gift and the size 39/40 fitted perfectly but when i ordered the size 39/40 online it was a bit small, i needed the next size up, don't understand why the same sandal in the same size has 2 different fit, 1 just right and 1 a bit small. If you intend to order these order a size up from your regular size.
