Wow, I though my armpit odor was the worst in the world. It really no comparison with you. I am currently using HIRCISMUS CLEANER, but as far as I know, it only can eradicates armpit odor, not for feet, it may works for your feet, I don’t known. You have to ask them. Their website is http://www.odorlessbody.com
Good luck to you and all of us who has bad smell.
