First you have to identify the cause what brings the smell..maybe it is because of ur shoes and socks..maybe they are tight fitting and don't allow enough breathing so watch what you r using..maybe it is the detergent you are using to wash ur shoes and socks..so try to use the non fragrance one..and wash ur feet with antiseptic soaps or maybe cloth soaps since they have less fragrance..fragrance can be ur enemy here..and other thing that you can try is soaking ur feet into salt and baking soda solution in the lukewarm water daily for 15-20 min..and vinegar can help too..using lemon on your feet after u soak it in the solution and leave it overnight can also help too..so try to be consistent..the main thing is consistency..alseram bleh endatakuartew..Good Luck
