The main reason that causes the feet to sweat is their high concentration of sweat glands. Medical Scientists have also linked it to over-activity in the sympathetic nervous system. You can deal with the situation by taking Botox infections, wearing furry slippers or shoes that are lined with fur and washing your feet before and after you put and remove your shoes. You should also visit a dermatologist for medical treatment.
It's important to make sure your feet are clean and that you get the dead skin off regularly. It won't stop the sweating but will stop your feet from stinking. Dead skin traps the bacteria and causes odor. Also, try not to wear the same shoes every day. It will allow them to thoroughly dry out.
