Feet have more sweat glands than any other part of the body. Together, they can produce as much as half-a-pint of sweat a day – the perfect breeding ground for the bacteria that thrive in warm, moist conditions.
Simple hygiene is very effective. Treat your feet to socks made from natural materials like cotton and wear properly-fitting leather shoes that allow your feet to breathe. Lastly, let your shoes dry-out properly before wearing them again.
