Smelly shoes is what you can always avoid as it’s embarrassing.
Let’s now look at how to overcome smelly shoes.
Examine the shoes. Are the insoles damp and causing the odour? If so remove them and dry them. Or replace them with insoles formulated to kill bacterial growth.
If the shoes are slightly damp, place them in the sun or near a heater and allow to dry thoroughly. Remove laces and lift the shoes’ tongues to fully air out the shoe. Put the shoes in a zipper-lock plastic bag and place them in the freezer overnight. The freezing temperatures will kill most odour-causing bacteria. If odour remains after the freezing, pour baking soda into the shoes and leave it in overnight to absorb the odours.
