My cousin Jake has smelly feet. Its not his fault, and for years we thought there was nothing to be done about it. Jake would go through several pairs of shoes each year and it seemed as though the odor was destroying them.
WET SHOES
One of the problems of course was that Jake was always getting his shoes soaking wet . Shoes need to be dried occasionally to prevent mold and bacteria build up. The best policy is to remove the laces and or open up the shoe as wide as possible and leave in it in the sunshine on a hot day.
BACTERIA
One easy remedy for killing bacteria is to put the shoes in a plastic bag and stick them in the freezer for a spell.
FLORAL INSERTS
When Jake visits my Grandpa however, the wise old man slips a strange insert into the young man's shoes. Grandpa fills a white cotton tube sock with equal parts kitty litter, baking soda, and peppermint tea leaves. He ties the end of the sock closed so it's just a cotton envelope full of sweet swelling herbs and powder - it won't come apart when he jams the tube sock into Jake's malodorous sneakers.
