Unfortunately, their quality showed over time. They came unstuck from the top and tore. I expected better durability!

Average construction material, compared to an older model I had. At first, they were tight and look like they are old. They are said to be made from recyclable materials, I don't know if the texture and appearance of the material is due to that.

Average to good. Light with a soft upper part inside that the foot goes into. It hugs my foot well and doesn't come off while walking. The only negative I find is that they are quite tight on me personally (I wear 44-45) but I believe they will loosen up a bit with walking. So overall, I think if you don't want the classic 1-4 flip-flop for 3-4 euros that wears out in a week, it's worth paying a little more to try these. Definitely not suitable for people with wide feet.

Average quality. After 3 months of use, the seams started coming off. Also, if you get them wet, they smell bad.

The left one does not fully touch the sole of the foot and it wobbles, it tightens the foot more and the size it claims is smaller than normal.
