I work in a restaurant, Im on my feet a minimum of 34 hours a week, and these didn't even hold up for an eight hour shift without causing blisters, and ripping near the toe area.

Pros:
-Hidden from view
-Stay in place

Cons:
-Cause blisters after wearing them for too long.
-Rip apart after an eight hour shift.
-Slightly tight, and a bit smaller than marked size.
-Super thin, cheap material
