How to choose a sports slipper

Slipper A Slipper B

My pair of slippers have worned out after servicing me for almost 2 years. So it's time to get a new pair. Which one should I choose? My guess, the one without the holes of course. Imagine wearing slipper B in a public toilet, on the wet street (where ppl spit on the floor, etc). I'm sure the dirty water will end up under your feet. The brands are not important, just practicality.
