Why do shoes stink when they are worn long?

There are only two reasons for foot odor (shoe odor), one is foot odor (shoe odor) and the other is shoe odor.

however, the root cause is that sweat glands in the soles of feet are densely distributed, and sweat is secreted in large quantities under the conditions of sultry weather, mental stress, eating spicy and hot food, etc., and bacteria on feet multiply and decompose keratin by using nutrients in sweat, and urea and lactic acid in sweat will give off a bad smell.

human common sense tells us that sweat itself is not smelly, but bacteria grow to stink. In a suitable temperature and humidity environment, bacteria grow at an alarming rate, and due to air tightness, it may take only half an hour to produce bad smell.
