After two weeks of use, I am completely satisfied.
Anatomical insole with a lift at the end of the foot (where the toes begin) to hold the arch in place.
It appears to be made of genuine leather both on the upper part and on the sole.
They have a light pleasant scent and do not smell after prolonged use

Fly flot. I have been using them every day for years as a dental technician. I change them every 4 years or so, only because they have worn out externally. They do not smell and they breathe comfortably. They are a bit tight in the first few days, but they quickly loosen up. I wear size 43 shoes and I also take size 43 in these

My first contact with slippers. I bought it to have a comfortable slipper at home. Nice, ergonomic, good quality, good size, I wear size 43 and it fits perfectly. However, the truth is that I expected it to be like a soft running sports shoe in the form of a slipper. It is comfortable but so far it is harder to step on than I would like and a bit heavy. If anything changes with use, I will come back.

Update1: after using them for a week, they have softened somewhat. They are non-slip, they squeak quite a bit on shiny floors, and this is somewhat annoying.

Update2: after a few months, I can say that at first it takes a little patience until they soften, nevertheless, I would still like them to have a softer step. I now only wear them with athletic socks because they hurt my little toe. The squeaking on the tiles stopped when I rubbed them a little with sandpaper.
