Unpleasant shoe odor is caused by the bacteria in your shoes. By killing those odor-producing bacteria you can easily eliminate the bad smell from your shoes.

To do just that, add a teabag in each shoe and leave it there for 1 to 2 hours. Tea bags effectively kill bacteria and thus eliminates the smell.

You can use any type of teabag. Black teabags are the most effective as they contain a high concentration of Tannin which is good at killing these odor-producing bacteria.

Once the odor is gone, wipe the inside of shoes, and let it air dry. Your shoes will be smelling as fresh as new.
