I have a terrible problem with smelly feet. I have to wear tennis shoes for work and work either 8 or 12 hour shifts. I have tried literally everything I can think of to help with the odor. I wash my feet everyday sometimes 2 or 3 times, I wear diabetic socks so they are moisture absorbant to try and cut back. I have all kinds of powders and lotions that I use.. nothing helps!! Any ideas???

Update: I just got new shoes last week and the problem is still continuing..
