I use them as work shoes. My size 10.5 fits √11 perfectly. (A bit big but for all day work it's perfect). They are soft enough. Not slippery. Not the prettiest, but very useful. I'm already ordering a second pair.
Pros
Very convenient. Breathable and lightweight. Exactly what I needed.
Cons
The anti-slip function may not work on all surfaces, which can lead to slips and falls.
