Your feet squirt into your socks something like a quarter to half a liter of sweat every day.  At the same time, you have skin cells falling off at the rate of a thousands every second from your feet.   So what you've got are all of the elements of the perfect microbiological banquet going on on your feet:  you have food in the form of dead cells, you have water in the form of sweat, and you have warmth.  All these things add together to make very hungry bacteria and fungus well fed. Consequently, they produce various chemicals, some of which are smelly.  But if you put these activated charcoal shoe insoles into your shoes, they soak up the sweat for a start, which means that there's less water to keep the bacteria lubricated so they don't grow as well, and they also soak up some of the noxious gases because they have a big surface area and they can adsorb those materials, which prevents them from being so pungent.  This makes your shoes stay drier and breathe more odor free.
