• It’s harmful for the foot health.
• It can cause injuries.
• It causes a distracting sound that is very annoying in quite places(Public libraries, education classes, …etc)
• I’ve never seen anyone who thinks they look good in it, and personally, I don’t believe it makes the wearer any more attractive.

I don’t know why men or women wear it and I think the only reason it was invented is to fuel consumption as they are usually not as durable as normal footwear.
