What should I do if my shoes stink and I can't wash them?

First, the simplest ventilation. After going home every day, take off your shoes and socks and put them on the balcony for ventilation. The smell will slowly disperse, so it won't smell bad naturally. Your shoes can be breathable all the time, and your socks can be washed together when you wash clothes at night, so that the breathable shoes and washed socks will not have a big smell the next day. Second, bask. Because of sweating, shoes in the room may smell wet, which will breed more bacteria and make the smell worse, so shoes should be kept dry. When the sun is fine, take your shoes out to dry for two hours, especially some sweaty sports shoes. This kind of shoes needs more drying. Shoes will become dry and soft after sun exposure, and the sun can also play a role in sterilization. Suntanned shoes will be particularly comfortable to wear. Third, change socks frequently. Fourth, pad a disposable mask. First, prepare a disposable mask, cut it open and take out the steel wire. Scrape some soap crumbs, put them in a mask, tie them with steel wires and put them in shoes.
