Update after the Summer
With the heat and the sun they shrank at least 2 sizes!!! They contracted as if they are heat-shrinkable!!!
First time I see this in shoes/flip-flops!!!
Unbelievable!!

As soon as the sun saw them for two days, they became at least two sizes smaller. One of them even a little more than the other!

I left them out in the sun on the balcony for a day and the material dried out and shrank at least one size!

Unacceptable.

In sports shoes, I wear size 47 1/3, but I bought them in size 47.5. They are at least 2 sizes smaller compared to the sports shoes. They are durable, but wrong in size.

Very good, but for potential buyers - we buy 1.5 sizes larger than our regular size because they are narrow.

Very high quality, one of the best and most comfortable I've ever had. I usually wear size 44-45 slippers, so after reading the comments, I got size 45. They are not tight, they are comfortable, just a little bigger than my feet. I highly recommend them

Thank you for the comments because they really helped.
I usually wear size 43, 43 1/3 for sports shoes.
I bought size 45 and it fits exactly in length. Generally, it is bigger than it appears in the photo, but personally, I prefer it as a slipper, especially for those that if I had taken size 43, they would have been tight.
The cushioning is soft and personally, I don't mind the design because it feels like it has orthopedic insoles.
I will come back if something bothers me. 4 stars because if I hadn't read the comments, I would have exchanged them.

Okay, I can't say they are extremely comfortable overall... Same size as the shoes in under armour, I got them in 47.5 and they fit well in terms of size, but they are annoying to walk in, especially if you have thin arches or sensitive feet.

I again experienced exactly the opposite with the size. Take them one size smaller. I got them in size 46.5 while I wear size 47.5

All good with the slippers, very beautiful, very lightweight, worth their money, but be careful with the size. Other friends have mentioned it, but there is really a problem with the size... 1 size bigger and if you have a wide foot like me, 1.5 to 2 sizes bigger. I wear a size 43 and I bought size 45.

I have had them for two years and have worn them everywhere. In the sea, river, dirt road, tiles, rocks. They don't slip and haven't suffered the slightest damage. They even fell from 15m and nothing happened to them. Totally value for money. One to one and a half sizes larger.

While it is a good slipper in terms of being seamless and durable, lightweight, nice, everything is fine, they have made a mistake with the size.. their size 45 is actually a 44, not to mention exaggerations, maybe even a 43.5.. if someone has the opportunity to try it on in a store first to see the size, otherwise when ordering, at least go +1 size larger than what they usually wear in regular brands... And it's absurd because sizes are supposed to be standard.. size 45 should be 29 cm.. now how they manage to do this and why..

They are definitely worth it, it's like wearing tanks in front of motorcycles compared to other slippers. They are also very comfortable, especially for my wide feet. Value for money and I conclude with under armour = quality
