please help! foot odor

No matter what I try, my feet always stink! I'm at a loss, and really dont know what to do anymore. I have tried baking soda in my shoes, washing my shoes, putting them in the freezer, using foot odor powder, using the shower-to-shower powder and rotating between tennis shoes every other day. I do wash my feet and SCRUB them. But it seems it is more my shoes than my feet. Flip-flops smell even worse than my actual tennis shoes. I've also rubbed anti-perspirant on my feet. Nothing seems to work! Please, please help I'm sick of stinking and I'm about ready to pull my hair out. Tweet
