The only good thing they have is that they don't slip at all, neither on water nor on oil that has spilled on the tiles.
They are comfortable and not at all relaxing.
You feel like you're standing barefoot on concrete.
Your feet are sweaty the whole time you use them. (No other shoe has done this to me)
And since I couldn't find any other solution, I would sprinkle powder on them... but nothing... so much moisture that the powder got muddy... I wouldn't recommend them nor would I buy them again.
