I wear size 47, I bought size 47 and the slippers are like size 50! They are even bigger than flippers. I really can't advise you how many sizes down to get, it's better to look at others... Even if you get the right size, they don't fit well on the foot. I'm crying for my 18 euros

This specific flip flop has been worn from a simple walk on the beach to hiking (2 times) on rough, uphill terrain with large rocks. In all cases, it performed well, even in situations where shoes were needed. I don't know if I got lucky with this particular pair being well-made or if all pairs are like this, but one thing is for sure, I would buy it again without hesitation. They are truly worth it compared to flip flops from other companies that produce similar products, either of equal or higher monetary value.
