Unpleasant odor coming from shoes is a problem that is, let's face it, quite common.
This is probably why there are so many ways to combat this problem.
According to one of them, the problem can be solved by freezing.
Yes, to eliminate the smell of sweat coming from your sneakers, or the "aroma" inherent in the shoes themselves, the pair should be securely packed in a plastic bag and left in the freezer overnight.
In the morning, the boots should be taken out of the refrigerator and, if desired, smelled: your nose should sense the aroma of cleanliness and freshness.
If you don't have enough space in your freezer or you don't agree to use this life hack for some other reason, try using starch.
A few tablespoons of potato starch should be poured inside the shoes and left alone for 5-6 hours, or even better, as in the first case, overnight.
When the time is up, do not forget to remove the remaining product.
