Hello Sir/Madam, I have been suffering with foot odor problem from a quite long time. My feet smells bad even in open sandals and the person sits next to me get the foul smell. I have tried almost every sandal available in the market (leather,mesh,tpr, synthetic, synthetic leather, dr Scholl's etc) but still my feet emits bad smell. I have searched online and found that zinc deficiency may cause foot odor but don't know if I have zinc deficiency. I need an advice from an expert for my issue, thank you so much.
