6. Smelly Body Odor
Sweat is the main reason of body odor and just as smelly armpits are the result of sweat so are the feet. It must be known that both feet contain more than 500,000 sweat glands in all and these glands have the capability to produce sweat in excess of one pint. So you can imagine that if one does not follow good hygiene, how smelly the feet can be.
