This isnt a joke. They don't even smell that bad, if you like popcorn.

Is it a fungus?

It sounds like you may have a fungus or small amount of infection between the toes and or under the toes. Rub the feet with a good amount of shaving cream , that will usually take away the smell. Then I would suggest you get some antifungal cream at the pharmacy and use as directed. That should do it. Good luck and God Bless wtf they just dont have the proper hygeine and care. but feet does smell bad though. no its sweat atleast it dont smell like a rotten egg. Put some baking soda in your shoes and itll keep them dry and keep from smelling. LMFAO!!! ROTFLMAO!!! Did they pick up all the popcorn that fell on the floor the night before? The symptom you are describing sounds more like a yeast based foot odor. Think of sweat mixed with the smell of bread rising.

Most foot odors are caused by dampness and bacteria, fungus, or yeast. Use powder to keep the feet dry and this will help. Kind of like keeping your armpits dry to avoid body odor. Use Tinactin or some other remedy that stops yeast and fungal odor. If this doesn't work, ask your pharmacist.
