They do not have the authenticity mark on the bottom of the shoe, they were not my size, obviously they have a small size and slip on wet pavement.

I have had them for about a month. Very lightweight shoe, I have never worn such foam before. The upper part on the toes could have a lining, as I think it is easy to tear. Definitely not suitable for rain due to its construction. Currently, it has not bothered me at all in walking or posture. For everyday use, except for rainy days, it is great, depending on the usage. For its price, it is a very good choice, as I have paid 160 euros for a somewhat better quality brand. I highly recommend it.

After 2 months of use, the lining inside tore at the point where the big toe touches. I believe it's only a matter of time before the outer mesh tears as well. I bought them because they have a small protrusion on the side for arch support. However, in practice, they are not very comfortable, and after a long time of walking or standing, my feet start to hurt...
Purchased on sale for €35, the only thing I have to say is that for an extra €10-€15, one can find something much more high-quality on sale. This particular shoe is of a low-market construction.
