What is the best thing to do for smelly feet?

Soak: I recommend to soak you feet in warm water and black tea for 10-15 minutes everyday. Apply foot powder everyday to your feet and inside of your shoes. Bromohydrosis (excessive sweating and smelly feet )may need medication as well. See a podiatrist for possible prescribed meds.

Dry them: Foot odor is from bacteria, bacteria grown in our shoes and between our toes. You need to rotate shoes and socks ie. Never wear same shoes 2 days in a row. Also wear socks with shoes whenever possible. If your feet sweat excessively you can spray the bottom with underarm deodorant before putting on socks.

Smelly feet: As stated , this is a bacterial overgrowth problem. Washing with an antibacterial soap will help , rotating clothes as stated is a must , and using a product like clean sweep helps a ton . This product kills bacteria and fungus in shoes and I use it as part of my laser treatment protocol.
