Foot odor

Foot odor is because there are many sweat glands in the feet and it is easy to sweat. In addition to water and salt, sweat also contains lactic acid and urea. Under sweaty conditions, the bacteria on the feet multiply and break down keratin, coupled with urea and lactic acid in sweat, which will give off an odor. If the shoes are not breathable and air does not circulate, the odor will accumulate and become stronger, and the odor will be extremely strong.
