What to do with smelly feet in leather sandals
Take an appropriate amount of dehydrated alum or dry lime powder, put it in a small cloth bag, and put it in the shoes every night before going to bed.
We should also pay attention to the hygiene of the feet in normal times, pay attention to washing feet frequently, changing socks frequently, and rubbing the dead skin on the soles of the feet and toes, so as to keep the feet clean and avoid foot odor.
