It may be time to throw away those pair of sandals if

At times you may not want to wear shoes that cover up your toes or has a heel on them so you put on some flip flops instead.  Something that may feel a little more comfortable to you.  The thing is though that flip flops that look like the ones in the picture above shouldnt be choosen.  You can literally see the footprint of the persons feet from constant sweat built up over time.  Whenever you see that your flip flops look like this, just remember to throw them in the trash and by another cheap pair.
