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.

I noticed that bottle(s) such as these may harm you. Look at the red bottle that i used at the office. You can notice that the paint came off at the edge. Where it went? In my body, of course. My advice, try to pour your beverage into a cup instead of sucking it straight from the bottle. I'm unsure about the expensive ones like SIGG (blue bottle).Not sure whether i spelt it correctly or not. Anyway, the paint/spray looks tough and may or may not come off. I leave it up to you to decide.
