Although they are beautiful and comfortable, they are terribly dangerous. They slip incredibly. Wherever you walk with them, it's like walking on ice.
We're not talking about wet floors. There is a risk of death there. I almost got killed.
Unfortunately, they are dangerous, although in terms of comfort etc. they are very good

They are dangerously slippery on a plain floor, on tiles, on the road, everywhere. They have no functionality, only beauty. It's a waste of money. It's criminally bad. It will break your neck. Luckily, I never fell from them. After using them for three days, I realized they are only suitable for indoor use, in the bedroom or living room, and that's it.
