I have been buying these flip flops for years (I wear them all summer and wear a pair out every year) and the ones Amazon sell are the same as the ones I always got (in the UK, Croatia, Portugal...). The Tradicional are slightly different than other Havaianas, the material feels a bit less rubbery and the bit between the toes is a little shorter - which is why they are the only ones I will ever buy (the regular ones are too loose for me). I have never seen these sold in a box, they only ever come tied together with a plastic string. They are also always cheaper than the other types. I wear size 7 shoes and get the 39/40.
wasn't sure if these Havaianas would be ok being as they only cost me £10 . but how wrong could i be they fit perfectly and just the right colour i had seen them on another website for about £18 so a very happy customer .
I ordered size 3-4 and the sizing table said it equals EUR 37-38. Well it equals 35-36 like it says to be Brazil size. I always use 37 but in these flip flops my heels come over the sole in the back, not nice. Luckily my daughter can use these, I'm not sure if I'm going to order another pair for myself, even in this sale price they're a bit expensive for just a pair of flip flops.
