Is it normal to smell feet?

A:

No it is not normal to smell feet! In fact it is completely the opposite.

That depends upon what you mean by 'smelling feet'. It is normal for feet to produce an odor when trapped in a confined space such as a boot; it is not normal (though not abnormal, either) to sniff one's feet on purpose.

Sniffing another person's feet for sexual pleasure also isn't common in the population at large, but it is one of the most common of what are known as sexual fetishes.
