The smelly foot is a condition that is observed a lot by Podiatrists. It is a source of much concern for those who experience it (and the people around them!). The main approach to tackling the unpleasant foot odor is to lower the perspiration and stop the breakdown of the elements of the perspiration that lead to the smell. Odor-masking products can also aid in this case. https://ipodiatry.org/smelly-foot/4115/
