Wash them well, buy great quality socks and shoes that breathe. Cheap shoes, boots and cheap socks dont breathe well, your foot sweats and goes bad.
Also they make foot deodorant spray that will work if you use it.
Another thing to think about. No matter what you do for your feet, if you just put back on the stinky shoes, the bacteria will just go back to your feet. Once that bacteria gets into the shoes, its pretty much impossible to get rid of.
So here you go.
Step 1: Throw away every pair of shoes you own and start over.
Step 2: Buy High quality shoes and socks that allow your feet to "breathe"
Step 3: Wash and use a foot deodorant everyday.

I used to have to throw boots away after only a few months because the stink would get so bad I could smell my boots while I was wearing them. what I did was start with all new socks and new boots. every day I put alittle baby powder in them to absorb the sweat and I have not had a problem in almost a year. I finely wore a pair of boots out!!
Yeah, no kidding. If your feet smell that bad you might have something else going on with your feet. Try driving in your socks to let your feet breathe.
